Probably just an age thing, but this sort of stuff is where I'll give up and stay put with what I have.
I'm never going to talk to a gadget, in order to get news, weather, music or whatever. Even sitting on my own in the house. Just not going to happen.
Eleven years ago, (is that before even the iPhone one came out?), my car had voice control for the Sat nav, the climate control, and the audio system. I used it for the novelty value, three or four times, then never again.
As for lights, I usually just turn them on and off as I walk past the switch.
I think most people stop moving forward with technology at some point. I think talking to gadgets is where I get off.
