Indeed. "Go insane" is rather nebulous, too. Some sorts of insanity would be reasonably okay to live with, such as a phobia of paper. Others, such as compulsively cutting off your fingers or raging paranoia, might be a worse than an internet-free life.
Also, one has to balance the odds of a cure for your particular type of insanity being developed, vs. the odds of a cure for being without the internet for the rest of your life being developed. I'm not even sure what form the latter would take, really.
I think I'll keep the Internet and risk finger-chopping paranoia in the short term. But it's a tough call, as you say.

But if you didnt have internet you probably would go insane. At least if you were insane you'd have internet :P Why do you think your parents are like they are? ;)
