It is endlessly... amusing (?) to me, that we as a community spent decades trying to make it clear that our productivity is not easily measured because what we're doing is complicated and long running, only for AI to come along and suddenly LoC, Nx multipliers, tickets / week etc are held up as useful if not objective measurements.

The reasons we rejected LoC and other measurements have not changed (broadly: code output isn't important, quality output is). AI has all the same problems people do. But for whatever reason we are throwing what we've learnt away. It's kind of embarrassing.
