I don't know but I do know that the reason Sparc boxes and Solaris/SunOS is known by people who worked in business or academia is because that there were Intel PCs that let affordable computing reach the masses even while Crystal Tower computing existed.

Now it seems that affordable PCs are not what the Mega-Wealthy want so they will make every computing device capable of creating a challenge to A.I. as expensive as possible just like Sun did with their hardware.

They can do this because the market can't respond to make more competition. And tariffs make that worse.
