There is also an important third group:

- people that work outside Silicon Valley, where the entire company uses Windows centrally managed through Active Directory, and explaining IT that you need an Mac is an uphill battle. So you just submit your request for an RTX A6000 48GB to be added to your existing workstation

Those people are the intended target customer of the A6000, and there are a lot of them.

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.

There are some genuine, non-Dilbert-esque uses for AD. Where there really isn't a viable, similarly performant, alternative.
