Had it not been for UNIX taking over the Lisp workstations market, followed by the first AI winter, people would be using LispTorch today, and there wouldn't have been such a waste coming up with endless ways to speed up Python, and efforts like Mojo wouldn't even be a thing.
Not really the "fault" of UNIX. The Lisp workstations would have been just as unpopular without it. They were insanely expensive and the idea of a workstation was ahead of its time, not to mention the other "unneeded" extras like GUIs, a mouse, and the photo editing and 3D modelling suites. It was plainly uneconomical.
