I simply don’t need a lot of AI. I would be very happy with a futuristic UNIX workstation with lots of development on the kind of things that used to get everyone excited about computers.

What things? Apple doesn't really cater to the type of customer who's excited about computers, or even UNIX. And I'd argue that Mac OS barely qualifies as UNIX anyway. Yes, if you dig deep enough you'll get the faint smell of UNIX, but the spirit is long gone. Anyone who appreciates UNIX(likes) has much better options available.
