This is indeed interesting, and I agree 100% with the remarks of a problem that does not exist.
Old heating timer systems and room thermostats just work.
You have a timer which turns the heating on and off perhaps 2 or 3 times a day. You have thermostats on each radiator so you can balance which rooms are warmer than others.
If you are cold you turn it up, is you don't need it, you turn it down or off.
There really just is no problem that needs fixing, what we have is perfectly fine for 99.9% of normal people.
Just like using an iPhone to turn your lights on and off, rather than use the light switch.
Yes, it's a cool trick, but in reality, people will just use the light switch.
This does very neatly lead us into the Apple Watch topic.
Is the Apple Watch another item, like this, that is simply something that is an answer to a problem that, for 90%+ of people does not exist.
Even mo-so in it's 1st gen current form, where it's just mainly an iPhone (you have to be carrying with you) accessory.
People have realised, they are carrying a phone, and have stopped (other than fashion) stopped bothering, with wearing a watch.
Do we need to move backwards and lumber people with a device from the past we have moved on from?
For sports use, yes sure, I 100% totally understand there is a niche market for sports fitness tracker type of devices, if you are running or half way up a mountain then you want to see data quick easy and fast, not get a large phone out of your pocket.
But average people in average situations during an average day.
Other than the initial "oh look at me, how great I look, I have the NEW Apple Watch" aspect.
Again, like the remote room heating, The Apple Watch is another one of those devices that's an answer to a problem that, for 90%+ of normal people simply does not exist.
And I mean ANY smart watch from any brand.
If (in the future) a Watch can be made that means you can go out without needing to carry your phone with you as the watch does it all (in a sensible manner) then sure. I can see some people going for that.
