"You're a genius!"

This afternoon I went to a show called "Love Song of the Electric Bear" which is about Alan Turing, who is considered to be a mathematical genius (he was very important in the creation of the computer). In the play, at least, he was a very odd person. Of course, in the play, he has a talking teddy bear...but I imagine that he was a bit eccentric (not because of his orientation, but more because of his obsession with his theories and everything). Which made me think of John Nash & A Beautiful Mind. Now I'm thinking, is being a genius a good thing? All representations of actual geniuses kinda make them out to be totally out there with social problems and all. Doesn't it seem like to be a bonafide genius making some serious super-important discovery (esp. a mathematical one) you have to be just a bit off? I mean, that makes sense. If you're going to do something new, that people don't think is possible, you have to be very passionate about it to run with your idea despite all the discouragement. I'm sure that there are plenty of "normal" geniuses, but then again...maybe not. I'm trying to find ones that are using Wikipedia. On my brief read-over, Einstein seems ok except for his wild hair & the fact that he married his 1st cousin (which I guess may have been normal at the time seeing as Darwin also married his cousin in a somewhat similar time frame). Beethoven appears to have had some psychological disorders...In short, I am ok with not being a "genius" and I wonder if telling someone "you're a genius" (without sarcasm) should really be a compliment...(and if it's said sarcastically, if that should be a compliment...=D )
