While there are many people "that work outside Silicon Valley, where the entire company uses Windows centrally managed through Active Directory, and explaining IT that you need a Mac is an uphill battle" I think these companies either don't care about AI or get into it by acquiring a startup (that runs on macs).

Companies that run windows and AD are too busy to make sure you move your mouse every 5 minutes while you're on the clock more. At least that is my experience.
