I don't like this argument. For one you're on "Hacker News," a forum for hackers who hack with (mostly) computers.

Keep in mind also that a lot of what we regard as essential today, say, the foundations of computer science (bits, formal language theory, algorithms) were once the trivial ejaculations of bearded professors in some ivory tower.

We need people dicking around in masturbatory enclaves solving puzzles, just as we need agitators and activists. I think it's unfair to say one group works at the expense of the other.
