And that's just unnecessary friction, which is a problem of politics, not technology. I do recall a time as recently as 4 years ago where it was difficult to find, for example, rack-mountable servers that could hold a large number of these GPU cards, but substituting for a mid-range PC with 2 or 4 of them would not have been an issue, even then. Cost would be higher but not necessarily outrageously so, since large server chasses often have startlingly large PSUs. It might be an extra 50% on top of that $3k, but that's still competitive, even with the pre-builds the article mentions.
