I used Claude Code to write a relatively complicated watchOS app. I know how to program (FAANG L5), but didn't really know Swift. I achieved a pretty good result for about $600, while a contractor would've cost much more.
Good question. I left my job to start something on my own so an AI help is really nice. Should note that AI does make many boneheaded mistakes, and I have to solve some of the harder problems on my own.
