I was at Microsoft until July of this year until I left for an SF-based company (not AI though). The difference between the two with regards to AI tool usage couldn’t be more different- at Microsoft, they had started penalizing you in perf if you didn’t use the AI tools, which often were under par and you didn’t have a choice in. At the new place, perf doesn’t care if you use AI or not- just what you actually deliver…
Presumably your new company isn't building AI tools, so they don't care what you use.
Imagine a developer in 1990s Microsoft saying "I want to use Borland C++ because it's better than the Microsoft IDE". Maybe it is, maybe it isn't, but that's not the point.
