This is very much an N=1 anecdote from a friend, but his manager has basically doubled velocity expectations for the team at his company over the last year. Everyone has to use Claude code because that's the only model they're allowed to use, and not using it means not hitting the arbitrary expectations.

Conversely, the company I am at has no such expectations, and we've got a legacy code base that LLMs aren't very handy in anyway.

So do I. What I'm finding is that they are now.

I've spent the last week tracking down bugs using Fable that have gone undiagnosed for several years. And this is a damned obscure legacy code base that runs on a proprietary 8051 variant. Guaranteed to be nothing like it in-distribution.
