> 20 years ago, I prided myself with keeping on top of almost everything in CS. Now, I can barely keep up with the names of all the cool tools out there. 20 years ago CS was smaller in scope, simpler, because there was less of it. We have more systems, more complex systems, and in some point the body of knowledge grew so large that one human cannot know all of it.
