> Is there any reason Jeff Bezos, Bill Gates, Mark Zuckerberg, and Elon Musk can't endow a Prize in Computer Science?

Even without searching, I'm sure they back a number of organizations that do endow various awards, scholarships, and so on. I doubt they could come up with a "flagship" one that would be as prestigious as the Nobel Prize, though. Our attitudes toward modern-day "industrialists" and their pet projects are quite different today. Whatever controversies surround the Nobel Prize, they would be many times worse for the Bezos-Gates-Zuck-Musk Medal of Merit.
