Ah, that's disappointing.  I wonder why he doesn't feel like he can just be honest and say, "I took a quick look at it, and here are a few typos, but otherwise it seems ok!"

I have some senior coauthors like that, and I honestly don't mind it.  Their presence is usually helpful in other ways, without having to touch a lot of manuscript work or research work directly.

Senior.

It's sad, because he's one of the most brilliant scientists i know. He did it for a lack of time, not a lack of skill. Having his actual input on the paper would have been so much more valuable.

He seems to have developed a weird fascination for AI which keeps him from noticing some of its obvious shortcomings. One needs time to learn how to use AI well. Time he does not have.
