I really do believe the next big disruptor (on the scale of something like space travel or the internet) is going to be in our ability to harness brain power to directly manipulate our world.
There is so much research going on and a lot of it is quite advanced. Some day we'll put it all together and the results are going to be amazing. Not only in curing disease, but in fundamentally changing how we interact with our machines.
I can't wait.
