You seem to be confused. Yes-men were often rather smart. They said yes in a ploy to get what they wanted, like a promotion and higher pay.
Lemmings, sheep and such weren’t necessarily not thinking, they are drawn to being part of a social group and follow it for a sense of belonging. They often spend a lot of time thinking about how to stay part of the group.

There are of course people who just have low IQ. But I assume you aren’t belittling them for using AI to help them do what they can’t.

I sometimes think of Patrick Stewart the same way as Huey Lewis and the News. Patrick was a stellar actor, and he prefered theater. But Hollywood paid the bills. Huey was energentic, charismatic and put on a great show. He and the News had a pasion for soul music. But pop music paid the bills.
Both got to follow their passion while making it big in something related. And good for them.
