> Artists understand that AI is bad for art. Why don’t programmers understand that we are artists?

Because the vast majority of programmers are bad artists, they just did programming for money. Only few actually cared about true craftsmanship, readability for every level of programmers while maintaining maximum efficiency, true passionate programming or quality open-source without caring how much money earn. AI makes bad artists the best as they don't care the taste but quantity. Same applies for bad programmers.

> they just did programming for money

Very reductive. I would consider myself a pretty mediocre programmer, but worked with a lot worse. I care about making useful things for other people. I care about quality but less so than utility. If I ever get to the point to not need to worry about money, I will still focus on utility over any artistic notion of the code that produces that utility. Sometimes those things align, sometimes they don’t, but I’m much happier shipping a messy to maintain thing that is useful to lots of people, than something that is algorithmicly elegant.
