The author seems to be complaining about the fact that you can't make a pet hobby project succeed purely out of technical excellence. First of all welcome to the club: musicians and artists and people of taste have long lived with the constant pain of watching the majority of people consume crap. Secondly: it's not true that products cannot succeed on the basis of pure technical excellence. Figma, TigerBeetle, and much software of the highest class have won the market on the basis of technical excellence, and it's the kind of thing amateurs with AI will never be able to build. You need to find an audience with a real problem and then produce a technically superior solution that an amateur with AI cannot.
