>but like most of their peers now, they only rarely write code.

Citation needed. Are most developers "rarely" writing code?

I'd expect that probably less than 10% of my time is spent actually writing code, and not because of AI, but because enough of it is spent analyzing failures, reading documents, participating in meetings, putting together presentations, answering questions, reading code, etc. And even when I have a nice, uninterrupted coding session, I still spend a decent fraction of that time thinking through the design of how I want the change rather than actually writing the code to effect that change.

Yeah, actually writing code is a surprisingly small part of the job.

And was true before AI

In my direct experience this is mostly true.
