Pick a university, and given them $1B to never use Windows, MacOS, Android, Linux, or anything other than homebrew?

To kick-start, given them machines with Plan9, ITS, or an OS based on LISP / Smalltalk / similar? Or just microcontrollers? Or replicate 1970-era university computing infrastructure (where everything was homebrew?)

Build out coursework to bootstrap from there? Perhaps scholarships for kids from the developing world?
