Given Apple's current locked-down trajectory with the Mac, the Mac Pro was gonna die eventually, and it's for the best that it does given it was reduced to little more than a massively overpriced Mac Studio grafted onto a useless PCIe backplane; a $12k grift, basically.
PCs at least are still modular and expandable; for now.
I thought there were already some M-series iPads that gave some actual workstation laptops a run for their money though.
iPads have always had the problem of having waaaaay way more compute power than they were ever capable of utilizing.
