For that last point, as a graphic designer competing with the first generation of digital printmaking and graphic design tools, I experienced the opposite. DIY people and companies are DIY people and companies. The ones that would have paid a real designer continued to do so, and my rates even went up because I offered something that stuck out even from the growing mass of garbage design from the amateurs with PageMaker or Illustrator. I adopted the same tools and my game was elevated far more than the non-professionals with those tools further separating my high value from the low value producers. It also gave me a few years of advantage over other professionals who still worked on a drawing table with pen and paper.
I'm glad it worked out for you, but the testimony is objectively somewhat anecdote.
Opposite to your testimony, I know one designer who's an out sourced contractor for a game company. The last time we talked, he's genuinely worried about generative AI, and witnessed layoffs due to the expectation that such tech would replace workers (specially ones who has singular function).
So, yes, there are people who's livelihood has already being negatively effected by AIs. Maybe those are just "DIY people", not "pro-like-me", maybe.
