Kinda think Asahi is not going to fair too much better in this fight. It’s an interesting exercise but most people won’t buy a Mac to use Linux. The only reason I’d buy an overpriced piece of hardware is because it can run Linux very well. But apparently people like me is negligible.
The big difference I see is in the chip. The PowerPC arguably had its benefits (vectorization) which made it super attractive for bioinformatics, etc., and a lot of that software was Linux-based. People could either buy a super-computer or a G4 (or a cluster of G4s) and get the work they needed done for a fraction of the cost. MacOS (and OSX) were behind on a lot of this stuff compared to Linux then.
Today from what I see the M3-M5 chips are a big leap forward compared to their competitors, and it just happened to hit at the same time LLMs became popular. I imagine there are some similar, specialized needs with the M[1-5] chips that might benefit from Linux but with OSX's stronger BSD underpinnings it's a different world.
