They present an interesting take, though from what I've seen myself, most "brain fry" comes from the transition from being a programmer to being a reviewer. A lot of software developers I know loved writing code, but now mostly supervise the output of AI tools. But the problem is that while they loved developing software, they never "signed up" for being a full-time code reviewer, which is what they mostly do now.
Before you had a team of passionate developers - now you have a team of prompt engineers and code reviewers that perform their duties with much less passion than they used to. I think that a lot of the "brain fry" comes from people suddenly doing very different things that they used to do.
