> At Meta, Google, Microsoft, and others, leadership says that AI generates a growing share of the overall code

Probably because they mandate its adoption. And while there are plenty of developers who will happily comply and see it as a good thing. There are others who will do it because they have to or risk losing their jobs.

It's a bit of a silly thing to claim. "We made everyone use it, so they did, and now adoption is going up!"

A lot of the code generated isn’t for the products shipped to users. At Meta someone told me that around 80% of generated code is for internal tools and dashboards (most of which have no usage).
