Honestly, he's wrong though.
I know tons of full stack developers who use AI to GREATLY speed up their workflow. I've used AI image generators to put something I wanted into the concept stage before I paid an artist to do the work with the revisions I wanted that I couldn't get AI to produce properly.
And first and foremost, they're a great use in surfacing information that is discussed and available, but might be buried with no SEO behind it to surface it. They are terrible at deducing things themselves, because they can't 'think', or coming up with solutions that others haven't already - but so long as people are aware of those limitations, then they're a pretty good tool to have.
It's a reactionary opinion when people jump to the 'but they're stealing art!' -- isn't your brain also stealing art when it's inspired by others art? Artists don't just POOF, and have the capability to be artists. They learn slowly over time, using others as inspiration or as training to improve. That's all stable diffusors do - just a lot faster.
