Which language to learn?

I know that this has to be a quite frequently asked question, but a group only gets more valuable members by helping people who want to learn. Currently I'm sort of proficient with DOS commands. Obviously you cannot create a complicated graphical program out of DOS. I've heard all over this board that Python sucks, which ironically is the one language most of my friends recommended learning. What language can I learn that is actually useful?

I come to /prog/ for you guys are the only assholes on the internet that will bash other languages if they do suck. Forums have to be 'unbiased' and 'neutral'.

No, I hate python because all the CS college kiddies that only know a single language talk about how amazing it is and how shitty all other languages are.
Seriously, it's a pain; these fuckers have never even used a non-python language and yet they consider themselves EXPERT PROGRAMMERS who know everything about everything.
Of course, this kind of arrogance and blatant stupidity is the same reason I hate /g/.
