Any technology is what you make of it. Many people have a laptop. The most many will ever do with it is browse, watch a few videos, Skype and play Candy Crush on it...and this is on a machine that many scientists from yesteryear would have pimped out their own mothers to get a day of compute time on.
I personally use a smart watch for a lot. I don't think the problem is with the concept or the technology. It is with people knowing how to integrate it into their lives.
