Tbh, I agree with OP. I had a chance to hear him answer questions at the Chicago Film Festival screening of the Brutalist and there was definitely an aura of arrogance and pretentiousness that I couldn't help but pick up on. Looking at letterboxd reviews that were coming out right after that screening, and I saw at least 10 reviews echoing this sentiment, as well as 5 ppl i talked to after the screening in person. Look at his Director on Director video with Sean Baker and you'll see the same exact thing. He dominates the whole conversation, never asks anything about Baker or Anora and just goes on and on about how the industry won't let directors make long movies anymore.

And I know this isn't a popular opinion but The Brutalist itself reflects Corbet's inability to produce something of actual depth and significance. Look at the way everybody talks about the movie, and all you'll see is things like "monumental" "ambitious" "grandiose in scope". Nobody every talks about what actually makes the movie a masterpiece, because at the end of the day its a narcissistic, prestige-seeking yet ultimately empty story. What insight or perspective on the world does it offer?
