Why do you think it will destroy hobby? I think it will increase. When I was a child I wanted to have map editor or tools for modyfing closed sourced favorite games but for me it was not possible. Low level programming and reverse engineering is not for me (but maybe I will get into it soon) so I am happy about tools built for agents. Maybe one day I will decompile and extend favorite games without spending several years with or without success. LOL, I am not sure if I want to do it by hand.

And ihmo programming, math, doing music or anything else still can be hobby - with our without AI. Do not be worry, you do not have to use AI for your hobby stuff. You can still code, create from scratch crappy personal frameworks/libs and so on.

I only want for times when local LLMs/AI are powerful and available on average hardware, so I could use it for my personal stuff without monthly payments. I wish doing so many things on my own.
