If you believe that Moore's law is only on life support and not totally dead, there will be more processing power to harness in the future. The number of researchers and investment are clearly growing very quickly. The models used can endlessly be improved.
But on the other hand there are so many things that even today just aren't captured as digital data. I work as a mechanical engineer and there are many nuances to mechanical design that appear nowhere in print (or youtube video, or blog post for that matter). Learning these things takes a complex combination of of sight touch and intuitive leap. Even unsupervised learning requires some input to feed the net. I just don't see where it will come from.
Anyone think I'm way out of line here?
