Self-driving cars would be fantastic, but I'm still waiting for a cure for cancer. Maybe better information processing during this revolution will speed that up, who knows.
I'm not sure what bitcoin has to do with the other things mentioned in the OP, but then again I'm far from a computer scientist.
In the field of biotechnology, for instance (I'm a bias microbiologist), we are currently finding ways to produce more variants of food with minimal amount of resources used as a catalyst.
Now
that's what I'm talking about. I'm not kidding about the cure for cancer thing. And in general it seems like there haven't been many breakthroughs in medicine in quite some time, although having oral medications for Hep C is a great thing, and the fact that HIV is no longer a death sentence. Maybe I'm just being cynical. But I do agree that a breakthrough in your field of microbiology is waaay more important than one in financial technology. That's my opinion, but I'm also biased toward science as well.
