You're saying two very different things. Nobody actually wants this is not the same as nobody is actually moving forward to achieve this. Performance is something like a tragedy of the commons. Because everybody is just doing what's in their own short term interests, but the long-term consequence is where we are today: you'd need what would literally have been a supercomputer, not that long ago, to run a word processor.

It's kind of funny to imagine this parallel world where you send a PC of today back to the 70s. Whichever government got their hands on it would be keeping it ultra classified and hiding it away, like it was some device, too dangerous for the public, that could computationally solve any problem imaginable, create anything imaginable.
