I've often wondered the same thing, but being smart isn't a guarantee of being correct. Hawking spent a career searching for a unified theory that he now claims doesn't exist. Is he not smart? Actually, studies have shown that the more intelligent a person is the higher the likelihood that they will defy common sense in search of their own intellectual gratification. If you went to a major university in the US, that wasn't a military academy, then you were most definitely subjected to loads of liberal indoctrination, and you probably don't even know it. It's a sneaky recipe. A little political correctness here, a dash of environmentalism there, a heaping teaspoon of marxism all rolled into a casserole of insecurity, jealousy, and hatred for anyone who doesn't think the same which can eventually lead to doing stupid things like DDoS-ing a major media website. :-)
Of course, you could be 100% correct and the academics may be smarter and know what is best for humanity. I'll concede to that, I certainly don't deny that there are tons of really smart people out there (most way smarter than me), but I do question their motives. The fictional character Q (Star Trek) had limitless knowledge, but he was adolescent in his behavior and his motives were questionable.
