I would assume any project that has more than a handful of contributors to have AI-assisted code in it.

I’m probably living in my little start-up bubble, so my view is probably skewed. The majority of commits I see have not had any code written by humans. Planned, specified and reviewed by senior developers with fancy degrees and a decade of experience in average, though.

Things move fast, but I’m sure a lot of older and bigger organisations are taking it slower because of the legal unknown.
