Robots will *never* live up to the hype. Hype is there to get outsiders excited about something. I'm a robotics researcher, and even *inside* the community, people hype things in order to drum up interest. That's the point of hype.
The fact that things are sometimes overhyped doesn't detract from the fact that significant advancements are being made.
You don't think that having a main wallet containing all of your real money that you tied to a sketchy "financial institution" will reveal your identity when it's the *only* wallet to ever make a transaction with the wallet that you bought your drugs with?
I think that autonomous vehicles will come and go, but they'll be around almost as long as cars with drivers. I'd bet that in the long-long term, urban planning will change such that cars become entirely unnecessary in all but the most remote places. I don't think that we'll ever become so densely populated that the world is one big city, but I'll bet that we'll see large high-rise condos become much much more common, and then it'll be a ride down an elevator to do your shopping and a walk or train ride to school.
It's not that suburbia isn't awesome. It's just the direction I kind of envision things going in. I could be wrong. This sort of radical shift in urban planning would take centuries, to take hold in the west.
