It's remarkable how many of these are self-fulfilling prophecies. You'll never use technologies that you have no idea how to use. You'll never need slick stuff you don't know because you won't get into situations where you would end up using it. And so on.
Prioritization is fine, but always be careful about rationalizing your own continuing ignorance of things that a lot of people claim to find useful.
(I actually ran into a min-cut problem in the wild today. I'm glad I recognized it as such, because it was kind of important, and I wouldn't have been able to solve it if I hadn't heard of graph flows and cuts. Hell, I might even have congratulated myself for having avoided spending time learning something so useless....)
