Compilers and Operating Systems Aren't the Only Reason We Need Operating Systems

I think we did talk about unicorns. I think my professors at Georgia Tech covered it pretty well. There were two classes that were Co-rec that you had to take at the same time, compilers and operating systems. You're always going to have something in the middle because no matter how much you think you're in runtime OS, web OS, all written in JavaScript, someone's going to ahead of time compile things so you get faster startups. We have to live in this world in between and say, okay, for this particular application, how much compilation do I need?
