I try not to call them GPUs, though it's hard to avoid.

But I didn't know they're not even capable of rendering graphics at a deeper level than just not having a video output.

It sounds like you definitely know some stuff I don't, but wouldn't it be smart for these companies to bid a bit more if they could, to make these builds with more resellable parts instead of using these crazy server rack combo platters?

I still think it's an economy controlled top down by the authorities that makes this "profitable," and when you boil it down it's just a fancy mathy story to distract from them making special stuff for themselves they don't want to share with us
