Wasn’t this the OS of freedom? Hmmm

Yes, you’re also free to shoot yourself in the foot. Do what you want, I’m trying to prevent you from hurting yourself, but you’re free to do so of you so wish.

I tried to install ISO image writer on Ubuntu, on my laptop.

Ubuntu already comes with an iso image writer.

Went straight to the package manager, no terminal bullshit, downloaded it, open button is greyed out.

What program? How did you run it? What are you trying to do, you need to be a lot more specific,

Fantastic. Stable version btw. Solved by uninstalling and installing another version available on the manager.

Package managers only have one version, so that shouldn’t be possible.

Linux is literally problems after problems after problems.

Again, at least once you didn’t installed it via the package manager, so at least once you shot yourself in the foot. I’m guessing it was the first time, and you installed a snap/flatpacks which maybe required especial permissions for accessing USB devices.

Like, download the APK, enable Unknown sources, tap on the icon? I don’t use android since 2017 but i’m pretty sure is the same, isn’t it? Not an happy comparison.

Yes, it’s the same, try explaining that to your grandma who doesn’t know how to answer a call and you’ll quickly tell her to first learn to use the basics before wanting to enable external sources and installing random stuff from the internet.

When i want to uninstall and app and all the dependencies connected to it (autoremove, right?) is Linux able to tell if some of those dependencies are necessary for other apps and “whitelist” them?

Yes, it keeps track of which things use what, autoremove removes things that were installed as dependencies but nothing else depends on them now. So for example if you uninstall Ark and that was the only thing using unzip, running autoremove would get rid of the unzip library.

If i got a beginner friendly distro how will i learn how to use linux properly?

That’s like asking how will you learn to swim if you start in a pool where you can reach the bottom. First of all under the hood Ubuntu and Gentoo are 99% the same, the main differences are philosophical, almost everything you learn for Ubuntu will carry over to any other distro. But if you try jumping straight into the deep end you will be overwhelmed. I mentioned Gentoo because you usually compile your own kernel when using it, how can you possibly learn Linux without compiling your own kernel!? But the majority of people who know Linux nowadays have never done so, and you shouldn’t need to either. The same applies to all the thousand paper cuts you’re inflicting to yourself for choosing a distro whose philosophy doesn’t include being beginner friendly.

So if an app is not a package manager i’m fucked?

For the time being, yes. But here’s the thing, if everything else is working, figuring out how to install a package manually is simple, but if you’re struggling with 100 other things you will be overwhelmed by it. Tell me, when was the last time you downloaded an .APK from a random site on the internet to install something on your phone? It’s the same thing.

I tried, it did nothing, i went online to search for a solution.

Weird, that used to work last I used Debian based with KDE.

This is mental. This shouldn’t be a thing even for pros. I need 15 minutes to install an app? Sorry i won’t go out this evening, i need to install an app and god knows what can happen.

Nope, I could install that in 1 min, because I know what I’m doing, so I know how to install dependencies. But you don’t, so you shouldn’t try to install stuff manually. For starters I would have added a PPA instead of manually installing a .deb, that way the package would get updated and apt would install the dependencies automatically, if that wasn’t an option or I was feeling lazy I would have just installed using snap/flatpacks, or if I had to install using a .deb, I would just use apt to do it to autoresolve dependencies. The fact that half of what I said there sounds like gibberish is the reason why you shouldn’t do it. It’s equivalent of someone who can’t even use Android properly asking you how to install an APK not on the play store, first learn the basics, then you can do complex stuff.

Well, yes, of course. Also i read some contradictions in your post:

No contradictions, let’s go over one by one

the installer only installs what is supposed to, but it needs dependencies to actually make the app usable.

Yes, but each dependency is its own package, so when you install one package you might be installing several. But if you try to install one package manually (via dpkg) you don’t get the packages it depends on (because dpkg is a glorified unzip, it doesn’t know how to fetch dependencies).

But that’s what package managers do, right?

Exactly, unlike dpkg, apt does know how to install the dependencies, so it would do it automatically.

Different apps could use the same libraries but also different ones, so the system could become bloated nonetheless.

Yes, but you’re missing the point, a single library doesn’t weight that much, a dozen copies of that same library do. You installed KDE, so you probably had these apps (among others):

• Dolphin
• Okular
• Kwin
• Konsole
• Ark
• Kate
• Etc…

The KDE library is 150/200MB, so on Windows each of those application on it’s own weights at least 200MB, so probably you’re looking at 2GB for 10 apps that use the KDE library. On Linux they weight very small amount, because all of them use the same KDE library which is installed system-wide. Maybe some of those also use other libraries, but if you install anything else that uses that same library the library won’t be duplicated the same way it is on Windows, where each installer is self-contained and brings all of the libraries it needs to work.

I don’t see how is this beneficial for the user.

There are two main advantages:

• Smaller footprint for the system. Like I shown installing all those packages on Windows would be a few GB, but on Linux it’s probably less than 1. Expand that to an entire system and you’ll see how you can have a full Linux system filled with packages occupying less than Windows with some programs installed
• System-wide updates. Imagine a vulnerability was discovered in SSL, on Windows you would have to manually figure out which programs use SSL, figure out if the latest version of it uses an SSL version that fixes that vulnerability, update them to that version, rince and repeat for all programs installed. Whereas on Linux a system update fixes everything. Same thing for new features or bug fixes.

And the disadvantages are:

• Complicated to install a package (because you need to resolve the dependencies). Which is not an issue if you use a package manager.
• Stuff might break if different programs depend on different versions of the same library. Again, not an issue because the package manager ensures everything is up to date so you get the latest for all apps and libraries which work together, but the moment you install something manually you need to manage this manually for that package.

So overall it has 2 huge benefits and no downsides as long as you use the package manager.

How? I’ve installed Debian with KDE

Mistake number 1, Debian is not beginner friendly.

downloaded the .deb from steam website

Mistake number 2, this is windows mentality, if it’s not in the package manager it’s too advanced for you for the time being. Beginner friendly distros would have had steam in their package manager.

learnt to install that using sudo dpkg -i steam_latest.deb

You could have also double clicked the Deb file, but this is a bad way, dpkg does not resolve dependencies, so you would need to figure those out and install them by hand, which can be tedious at best.

opened the app and i’ve been welcomed with a text inviting me to press enter to continue, pretty simple. The program downloaded stuff, steam is ready now. Not bad.

You lucked out, your system had all of the requirements met.

Repeated the exact same thing on Debian with xfce, that apparently doesn’t come with a software installer, nothing works. An alert says i need to download dependencies (i know dpkg doesn’t resolve dependencies). Where’s the “enter to continue”?

No such luck therez remember when I told you to use the package manager? This is why. Possibly missing something stupid like an i32 library, which you could manually install, but you shouldn’t, you’re making things hard for yourself for no reason other than wanting to avoid beginner friendly distros.

How is this my fault??

It’s your fault because like I’ve been saying since the beginning you’re trying to use Linux as if it were Windows and getting frustrated because it behaves differently. Trying to do this will be frustrating and you will become angry because nothing works like you expect, but you must understand that it’s not that things don’t work, it’s that they work differently.

You might be thinking this is stupid, an installer should install everything it needs, right? Nope, that’s a windows mentality, in Linux the main idea is that an installer only installs what it’s supposed to, any dependency should be system-wide. Why you might ask? Simple, imagine if every single GUI app had to include it’s own copy of the full GUI library it uses, your system would quickly become bloated, not only that but each program would open it’s own copy of the library using more and more memory, not to mention the interoperability problems between programs using different versions of the same library. In Linux the standard is for programs to use system libraries, it’s the convention, just like how on Windows it is to not (which has its own set of problems). This is why package managers are important, they’re not just downloading an executable and running it, they’re doing lots of stuff behind the curtains, all of it can be done manually, but like you found out it’s troublesome, so best is to avoid.

That’s one of the things I miss the most in Gentoo, having the packages of your system defined in text files so a fresh install was just copying those files and running an update.

I’ve tried similar things with other distros, but it’s never the same, the list of packages ends up getting out of date or ends up with too much garbage.

Currently I have a home server so I took the time to get an Ansible playbook setup for running, maintaining, and maybe migrating the server if needed. Since some stuff is also run on other machines that I have (update system, update some docker images I run in multiple systems, etc) I did setup some minimal packages that I need on my main system, it’s easy enough but I wouldn’t recommend using Ansible just for this (but if you also have dotfiles it’s a great tool for automating lots of the initial setup).

All of that being said, the reason I never bothered with this until I had a home server is that usually there are years between system installs, so even if what you had was exactly what you wanted the last time you installed your system, it’s unlikely to be exactly what you want next time you do. Since the last time I installed my main system I switched from X to Wayland, from i3 to Hyprland and then Sway, etc, etc…

I’ve never, ever got a virus on any of my pcs. I grew up with internet, since the ADSL days, i know my shit.

Therein lies the problem, you’re a windows expert, moving away from your comfort zone will always feel bad. It’s okay to stick to Windows, no one should be forced to use an OS they don’t like. But if you ever want to try again, I recommend taking a step back and accepting that for all your years of experience in Windows you are a noob here, and trying to jump into the deep end is more likely to get you drowned than learning how to swim.

Also I recommend dual-booting, so you have the safe heaven of a known OS to reboot into in times of need. Most of us started that way and dealt slowly with the difficulties in using Linux with a windows user mentality, until at some point we realized we were spending the majority of our time in Linux and Windows had become unusable because we were now thinking like Linux users. I’m sure that if I had tried to do what you did I would also be frustrated, so I completely understand you. But let me tell you something which you might not want to hear, and will possibly even get angry at me for telling you, but there’s a fairly good chance that the majority of issues you encountered were self-imposed. Linux has near infinite possibilities, but that’s like saying the ocean is nearly infinite, it doesn’t mean you should try to swim across it just because you’re used to doing it on a swimming pool, you’ll drown fairly quickly and get nowhere.

I see a common trend here. You seem to be very tech savvy and a windows power user, and get frustrated with Linux because you’re trying to solve problems with a windows mentality and failing.

Yada, yada, yada.

That yada yada yada is the most important part from my entire answer, choose a beginner friendly distro and stick to it.

Things to do to install an app on Windows: download the exe, double click on the icon, follow the instructions, done.

Nope, things to install an app on Windows: Open a browser, search for the program, click the wrong link, download a virus, go back, try again, find a more reputable site, download another virus, run anti-virus, discover your computer has been completely overrun by viruses, format, reinstall everything, find the right site, download the installer, click next 20 times, accept to have a new service running when you start your PC by accident, done?. You don’t do all of that every time? That’s because you know what you’re doing, I certainly don’t do half the stuff you mentioned for Linux.

Things to do to install an app on Linux: check the package manager

That’s it, if it’s not there you shouldn’t worry with it until you’re a bit more experienced. This is why I recommend beginner friendly distro a, they will have more stuff and possibly have snaps/flatpacks by default which should cover most of your use ases and are installed via the same GUI.

Man, there are hundreds (nonsense) distros out there, i need something like 3 lives to try them all.

Precisely my point, don’t. Pick a beginner friendly distro and stick to it.

Apparently not. I’ve saved a copy of the saves folder and simply pasted it in the retroarch folder on linux but the game doesn’t read anything.

Have you tried saving something new to see if we have the correct folder?

There were no errors. Screen went black and then everything was reset.

That’s crashing, there should be some log somewhere, can you reproduce or is it random?

This is actually fun: i have Ubuntu Budgie on my laptop and i was trying to create a bootable win10 on my pendrive with ventoy given that jesus christ woeusb is super complicated to install with all those manual dependencies installs and woeusb-ng gives problem with python. Installed ventoy, copied the iso, pasted it, nothing shows up in the drive. Copied the iso again, pasted it again, file already existing. ???. I’ve extracted the drive, plugged it back in, nothing. Extracted it again, plugged it in on my desktop, iso is actually there. Wtf is wrong with linux?

Did you installed Ventoy properly on the drive? Did you unmounted before removing the first time? Otherwise you might have corrupted the file, remember how people always say to eject before unplugging a USB drive? This is the reason, the GUI that shows you copying stuff is just a FE to the calls to the kernel for writing, the kernel actual writing to the disk is done afterwards, so even after the GUI closes the file was not totally written. Again, regardless of OS, unmount/eject drives before unplugging them. Also is your desktop Linux or windows? Does the bootable drive works? You need to learn to provide more information if you expect help, saying “stuff doesn’t work, what’s wrong with Linux?” Will get you a lot of answers of the type “the problem is between the keyboard and the chair”.

What’s wrong with Ubuntu/Mint/PopOS/Fedora or any of the distros usually recommended? They’re easier to maintain and more up to date than Debian

Replace Arch with Ubuntu and the answer is yes. Arch based that’s not a good idea.

The reason is that in 6 months lots can have changed, and Arch is not guaranteed a stable base, so updates might assume you have certain versions or things might break because you should have done a middle step during the upgrades that you didn’t which is now buried in months of update news in the wiki.

If you want to only update your system every six months, Arch is not ideal, it’s likely to work, but not guaranteed.

So i really wanted to ditch windows once and for all

Why?

so i’ve tried Linux for a week trying different distros (debian, manjaro, ubuntu, opensuse, mint)

Why? Choose one and stick with it, preferably a beginner friendly one like Ubuntu or Mint.

and first of all why? Why are there so many distros out there?

Because different people like different things and have different opinions. Some people like to have the latest packages and so they choose Arch, while others prefer to have a stable system until they want to upgrade core packages and so they go with Ubuntu.

What’s the difference between debian + kde and manjaro + kde?

One is Debian based and the other in Arch based. Debian uses apt, Arch uses pacman. Debian has a slower release cycle to ensure compatibility while Arch has a faster release cycle to ensure the latest versions of things are available. Like these there are thousands of small differences between any two distros. It’s mostly philosophical, so just pick something beginner friendly and stick with it until you find a reason to switch.

They look the same, they work the same. I don’t get it.

They don’t work 100% the same, that’s like saying that a car and a truck are the same because they’re both painted black and have a steering wheel. Under the hood they’re very different.

Also why do things have to be complicated?

They’re not, they’re different. Doing stuff on Windows is also complicated if you don’t know what you’re doing, excepts you’ve had years of experience, in a few years Linux will feel easy and Windows complicated.

I’ve installed debian, installed calibre to manage my ebooks, created a library from an existing library on my hard drive (not the one with debian installed), ERROR! All the files are read-only.

Is the entire hard-drive read only? How did you mount it? What format is it on? You’re skipping a lot of important questions, that if you had answered (or asked about this issue) you would know the problem. My guess is that you don’t have ntfs-3g installed and the drive was NTFS.

What??? I’ve followed multiple guides on how to change permissions and finally solved the problem.

How? This might give us an idea of what was wrong with it.

Now let’s restart my pc. files on the hard drive are read only WHAT???

Yes, makes sense, did you applied a permanent fix or a temporary one? Since we don’t know what you did we have to assume you did a temporary fix, so it’s like asking why did Firefox not opened after I restarted my computer if I had open it before.

Fuck debian, let’s go on manjaro.

That’s a bad reason to switch distros, if you switch distros every time you run into something you don’t understand you’re going to run out of distros fairly quickly. Let me tell you right now, EVERYTHING one distro can do another one can, no exceptions. Something not working is a bad reason to switch distros unless you know why the other distro makes it work and are okay with the philosophical differences between distros.

No problems at all on calibre. Managed to create the library as easy as i did on windows. My question is: where’s the fun in this?

The same thing that’s causing you problems is an awesome feature, Linux is very modular, you can build yourself your system exactly the way you want it. That is very fun.

It’s just problems, after problems, after problems and i didn’t even start gaming.

Well, yeah, it’s an unfamiliar thing, I feel the same every time I have to use Windows.

I mean i tried installing retroarch and importing my saves but of course nothing works.

Why not? AFAIK RetroArch should have cross compatible saves.

Read this guide, read that guide. Nope. Nothing works. Ok, fuck retroarch let’s customize the appearance of my desktop: move some icons on the panel, center this, adjust height, move this on the left, spent 30 minutes tweaking, very nice…

Did you saved in the meantime? Let his be a lesson, save often, you never know when something will happen.

kde crashes, all back to default.

That’s weird, I don’t remember last time KDE crashed, but then again I’m not using Manjaro so maybe the current version there is broken? What was the error? Did you submitted a bug report? That might be an important finding.

Let’s download some apps. I want as many apps that i already know as possible. Let’s see if jdownloader is available for linux. Yep there’s one. Nope, not for manjaro (officially). There’s a AUR package available. Nice.

Not nice, don’t use AUR on Manjaro, you will break stuff.

What do i need to do to install a AUR package? A wall of text on the wiki, 20 minutes videos, yay.

That’s because AUR is not meant for people who don’t know what they’re doing. It’s dangerous and unstable, the way to get an air package is to build it yourself, the way to get an automated tool to install them is to build the package for it yourself, this should prevent people who shouldn’t be building packages from doing so. BTW, Manjaro is especially unsafe because it has an AUR manager in their official repos IIRC, which btw is called yay, so not sure if that was a joke.

Ok let’s call it a day. Do i need to live another life to make linux work?

No, you just need time to learn something new, instead of jumping around thinking that things would solve themselves. If you had started with Ubuntu you might not had either of those problems, and if you had learned what was wrong with the first problem on the first distro you would know how to fix it in every other distro and solve similar problems, just like you did with Windows before and now solving things there is intuitive for you.

Steam vs GoG is a turf war, Epic vs anything will make people side with anything. The problem is that Epic has a shitty store with shitty features, and the only way it can compete with the others out there is to pay piles of money to game devs so they make their game exclusive to their store for some time. So usually people just ignore the game until it comes up in another store, and most of us have completely forgotten about it by then so when we find out just add it to the wishlist and wait for a 90% discount in a while. The game has been out for years at that point so a massive discount is expected soon and you already waited years to play, you can wait a bit more and save money, plus that teaches companies that signing exclusivity contracts is a shit deal.

GPU go with AMD, I don’t think I need to give much explanations here.

CPU you can do either, BUT AMD is usually better for multi-threaded applications (like video editing, modeling or animation), also an AM5 slot should last you years to come, AMD stayed with AM4 for a long time (I had most of the same PC for almost a decade thanks to that, it’s still the same AM4, but I had to replace the MOBO since the old one broke). So I would also choose AMD here, although Intel is not bad either, and if you get it in a sale it might come out cheaper.

One important thing, ensure the drive is CMR, the reason is that you likely want a RAID, and non-CMR disks take so long to read the entire disk that the chances of a second failure while recovering from a disk failure is significant.

That being said, how are you keeping track of the disks state? I built my RAID recently, and your post made me realize that I have nothing to notify me if one of the disks shows early signs of problems.

Nope, never bought any of the NFTs that were sold to idiot speculators because I understand the technology and see no value in owning a token representing a digital image. I feel that the rage of downvoting comes from people who got scammed because they didn’t understood the technology and now see it mentioned and think it’s all a scam, similar to how old people used to think emails were a scam because they sent money to a prince in Nigeria.

Cool, I’ve been out of the loop on crypto for years, just checked and you are correct, now the full Ethereum network, capable of beating visa in TpS runs at 0.0026 TWh/yr, i.e. 1/100x of the energy consumption of PayPal, therefore proving my point above.

Did you read the link you sent? It clearly states that only the amount of miners matter like I said before, the amount of transactions has nothing to do with it, you’re mixing the two.

The more people mine, the more decentralized it is

Wrong, decentralization is hard to measure, one person with a mining farm is centralized, while hundreds of people with their personal computer are decentralized but both produce the same amount of hash power. So you can have one person investing more and more in mining rigs increasing the total amount of mining power in the pool but decreasing it’s decentralization.

the more energy is necessary because difficulty is increased.

Yes, this is correct, if you have more computers mining you will have a higher energy spending.

The more transactions happen, the more blocks are required,

Wrong, there’s one blonc every 10 minutes, regardless of the amount of transactions that happen. Did you even read the link you sent?

the more energy needs to be spent to confirm all the transactions.

Wrong, the energy needed to confirm 1 or 1000 transactions is the same, and it’s related to the hashing difficulty established by the total amount of hash power, again, did you even read the link you sent?

The more it’s used, the higher the value, the more people mine.

Wrong, the value of an asset does not necessarily correlate with it’s use, for example gold is more valuable than dollar, even though dollar is a lot more used.

There’s a limit to the number of transactions per block as well, so no, your can’t just say “1 or 1000 it’s the same”.

Yes there is, but until that limit is hit the amount of transactions doesn’t matter. Also that limit is artificial and can be easily raised if needed, as it was done on Bitcoin Cash which can do hundreds of transactions per second more than Bitcoin, but because it has less miners uses less energy, thus proving you are wrong and the two are not correlated.

Visa is already able to handle 24000 transactions per second as is, no need for more infrastructure.

And ETH2 is theoretically capable of 100k, and that’s just one coin which BTW is PoS so nothing of what we talked about miners applies to it. No miners means less power consumption by the network as a whole.

Crypto uses 1% of the world’s energy production for a couple trillions in assets, the financial system uses 2.5% for quadrillions in assets, multiple thousands more than crypto, no, crypto can’t scale to that without a huge environmental impact.

Do you have a source for that? But also you’re measuring environmental impact as just energy consumption, and that’s very wrong, by that same standard I could say crypto is green because it produces no plastic, whereas Visa has huge factories to produce plastic for their cards, their card machines, etc. If you only focus on one environmental impact it’s easy to make anyone to be the bad guy, and for some reason people only see the Bitcoin energy usage and completely ignore that the energy consumption there is the whole story, whereas for other things there’s hundreds of factors pilling on top to generate the environmental impact.

Yes you are trying to greenwash crypto, just stop.

Again, I’m not, I recognize that PoW is an energy hungry method of confirmation, however it’s not the environmental catastrophe that the original comment said and if you take into consideration ALL of the environmental impact of alternatives (not just energy consumption) you will see that it’s not as bad as people make it out to be. Which doesn’t mean it’s good, but it’s far from an environmental catastrophe.

Also when you take into consideration that we were originally talking NFTs, and that’s mostly an Ethereum thing, and Ethereum is migrating to PoS, it’s even less of an environmental catastrophe.

First of all losing value and being a scam are not correlated, the dollar is losing its value compared to the Euro for the past year but it’s not a scam.

Secondly that would be an association fallacy, “X is a scam, X is an NFT, therefore all NFT are scam”.

Crypto energy usage goes up the more it’s being used and the more decentralized it becomes.

That’s wrong, crypto energy consumption has to do with how hard is the PoW difficulty, it does not correlate at all with usage or centralization, it’s only related with security, i.e the more energy it consumes the more energy someone would need to use to attack the technology.

But the energy needed to mine 1 transaction or 1000 is the same. There are problems at scale, but power consumption is not one of them.

Centralized services like Visa can increase the network load while barely increasing the energy requirements.

Not really, they need more servers to process more transactions, but cryptocurrency can scale up much more easily because the whole infrastructure from consumer to miner is decentralized.

Crypto bros always forget that to replace the banking system, crypto would need to replace the infrastructure as well, but because of decentralization it would be less energy efficient for the same result.

That’s what most people fail to see, the infrastructure for a scale at the size of visa is already in place for crypto. So there wouldn’t be an increase in power consumption by mass adoption, only by miner adoption, and that’s a difficult thought to grasp, it’s like if everyone could borrow their computer to visa or Mastercard to process their transactions, the amount of people wanting to offer their computer to visa/master would define how much resources they use, but an increase in visa users doesn’t mean an increase in visa borrowed servers and vice-versa.

You can just stop, there’s no way to greenwash crypto and decentralization. The amount of transactions happening on all crypto networks at the moment could be handled by one server if it was centralized. There’s benefits to it, stop trying to sell it as being green, it’s not and never will be.

I’m not trying to green wash, but crypto is not the environmental disaster the person claimed, especially not when you take into consideration PoS and newer coins with different validation methods.

No, there isn’t, but there are advantages to it as well, just like how a database has advantages over a paper folder.

An NFT can’t be transferred by anyone other than the owner, and ownership can be verified independently.

Here’s an example of a use that would be very cool and would take advantage of it (even though I know it’s unlikely to happen). Ownership of games, some games are sold on different platforms, to verify the ownership of the game (or DLC, or cosmetics) games have to verify with first party services (like PSN or Steam), which means that for the most part you need to buy games on each platform individually, but if platforms used an NFT for it games would be buy once play anywhere, and they would allow you to sell or even borrow games, and no company could prevent you from doing so. Which is obviously the reason this will never happen, but it’s a nice idea.

That being said there are downsides to it as well, such as a person being the full owner of stuff means that a person can lose the key and therefore lose access to the house, or that scammer can steal everything, whereas making you sign your house to someone else is a lot more beurocratic, which serves to protect you from you.

Just to be clear, I’m not a “we should use NFT for everything” type of person, in fact I don’t think there are many use cases nowadays that are worth using it, but the technology is interesting regardless, and solves the problem of how to prove ownership without a centralized trusted organization.

Do you consider a deed to be proof of ownership? A stock? The registry of a car? They’re not inherently proof of ownership, they’re just pieces of paper or entries on a database. If you go down the road of what is proof of ownership then no technology we have is able to prove it.

The thing is that NFTs you can prove ownership of the token, if the token correlates with something, e.g. if the DMV stored car ownership in a Blockchain, NFTs could be used to represent car ownership in a secure and decentralized way.

There are some valid points here, and I agree that the energy could be used elsewhere and that green energy is not entirely green.

I even agree that for most cryptocurrency as they are now the cost per transaction is higher than alternatives. However the technology for cryptocurrency, especially with PoC can be a lot more efficient in scale. To get an idea of it you can look at Visa, which processes 1700 transactions per second, BCH can do 178, so 10% of it, ETH2 is supposed to be able to process at least 20k, so 10x that amount. I imagine either of those coins pollute a comparable amount to visa when you consider everything that visa needs to operate (machines, cards, servers, etc). I feel that people don’t take these sort of stuff into consideration when they talk about the energy consumption of crypto. There is a discussion to be had here, but blankly stating that it’s an environmental disaster is fear mongering.
