It's reasonable to say this is wrong. But really, this seems like a tiny subset of users. Who bought a Mac Pro in 2023 after Apple Silicon had been out for 3 years already? Almost nobody, because it wasn't a real performance improvement by that time. For those extremely niche folks for which it was somehow still beneficial, they definitely won't want to still be using such a machine in 2028. They will have moved on to something like an M5 Ultra Mac Studio or whatever form the Mac Pro takes next.
