Computer Science is an odd field.<p>In the early 1970s, IBM failed to produce a multitasking, multi-user timesharing system that customers could stand.<p>Academic researchers developed VM, a virtual machines system. IBM's lack of a coherent operating system vision became a non-issue because a site could run different operating systems at the same time under VM. Circa 1980 a mainframe developer would spin up an OS instance in a VM, and spin up more OS instances in the VM if they want to run more tasks.<p>Although many think of mainframes as dinosaurs, it took PCs 30 years to get to that point.<p>There is part of computer science which is timeless, which is part of mathematics. There is also part of it that is so future-oriented, that the ideas will only bear fruit 20 or 30 years from now.<p>The 4-yr university aims to educate you for a lifetime, not to get your first job.
