The science is never settled. We should always be free to have new creativity, new conjecture. You'd never know where the best ideas are going to come from. And you have to take everything that's made in good faith seriously. A lot of theories as to why we're eminently going to create an a g i are based on a naive extrapolation of computational power. It's almost will do the induction of more and more computational power. So therefore, its couldn't start thinking soon.
