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'.

LISP + ASSEMBLY = HAHAHAHAHAHAHAHAHAHAHAHAHAHA!
In my experience, functional programmers (and this may be an unfair generalization) tend to not like dirtying their hands with machine-dependant code. LISP and assembly do not go together. The only LISP OSes I know of are either failures or were written for LISP machines. Richard Stallman decided that GNU was to be in C because he was the only LISP programmer he knew who would dirty his hands with the retched feces of porting assembly from one architecture to another.
