The well-known shadowy bias and conflict of interest of "I just enjoy experimenting with this new thing".

I do not think he's shilling; I think you misread the tone of my comment. Added an extra word now to maybe make the intent clearer.

That said, I do think "honeymoon phases" are a real source of bias. But then I don't think he's going through one of those either. He's been trying to leverage these models for a while now after all.

He might still be under a more general "tech adoption trend" bias, but at that point I'd say the lines become a bit blurry.
