Highly recommend checking out Andreas' other work on https://ertdfgcvb.xyz/. Probably one of my favorite websites of all time, his body of work is what complete commitment to an idea looks like. Couple cool hardware projects in there too.
It's amazing to be able to try a bunch of ideas with very minimal cost. That being said, AI code assistants don't have eyeballs and they often make things that don't look very good. Craft, polish and judgement still matter.
The entire crypto market cap is about $2.8T, which makes it about 75% as big as Apple. Would the same argument make sense if the author were to say Apple employees alone "push up prices for houses, resort hotels, and all sorts of other things they do with their money". Kind of a stretch if you ask me.
