After years of ignoring technology, I bought a smart phone and am in the midst of learning all the tools.
Yesterday I was just flabbergasted by a simple feat my first day of use.
I was a lunch with two friends deep in Potomac, MD and one asked me if I had enabled 'OK, Google' and we talked through it.
So I got in the car, and said, "OK, Google, take me home" and I got voice instruction that navigated me 36 miles to my house, skipping a couple of traffic jams.
On the way home, I figured I'd test it a bit and asked for the McDonalds closest to my home and it took me there.
Sometimes, technology is so close to magic that it's frightening.
