Most are probably too young to remember but nanotechnology was supposed to be the most super amazing thing ever.

    I’m not sure which era you’re talking about exactly. Graphene and carbon nanotubes can’t currently be made both big and perfect, and are lame when imperfect. Nanoscopic robots have problems with sticking together and jumping around due to brownian forces, and also are just very hard to build. Chemical-based robotics has been a crapshoot because quantum chemistry is hard. The last one has been tackled with machine learning pretty well recently, where natural biological analogues exist.

    As a result, about as far as we’ve gotten is nanoscopically fine dust. It has uses, but it’s only a technology the same way pea gravel is. It’s looking like a lot of the stuff nanobots were supposed to do is going to fall to biotech instead.

      Love the phrase “quantum chemistry is hard” because it makes it sound as if it’s difficult for the average person, but I can only imagine it means that the smartest people alive are struggling with it haha.

        Some Stephen Hawking level intellect is currently in a basement acting like an angry Jim Carrey because his math just chooses not to work.

        Even worse. It’s possible some of it can’t be done with any reasonable amount of classical computation at all, regardless of skill or knowledge. Quantum computers are badly overhyped, but that’s one thing they could definitely be good for.
