So you are a member of ZZ Top?

It’s about fun. You will find people who still like to dance with you, even if you think you are not a pro.

Also it is not about hard skill but about the level of fervency! If you dance with confidence, it will look even better

It is nearly instantly. Heat is generated in the pot directly, not in/on the stove, so there is nothing else which stores the energy, like the plates in older ones.

Since you are on Linux just Start it in a Docker container locally and you are golden :)
