A classic example of a solution looking for a problem.
'The internet of things' is another one. Fridges have been able to order food on-line for 20 years. The only problem is that they don't know what you want next, just what you have just eaten, or what has gone out of date because you haven't eaten it. Same thing with turning on the heating when you are due back home, but are stuck in traffic. If it takes 15 minutes to warm up your house, who cares if the heating is on when you get home, or you turn it on when you get home, or have paid 60p extra because the heat to the house at the same time every day and that was 30 minutes before you got home.
Just because we can do something, doesn't mean we should. And it certainly doesn't mean people will be willing to pay for it.
Although maybe the same arguments were made about the Dishwasher and the inside toilet.
