For me, it's not so much AI taking over and spelling the end of the human race. But more a case of the 'smart' world suddenly failing en masse and millions of people around the world ending up living in a house where they can't do anything — partly because everything has failed, but also because they simply don't know how to do anything because they are used to so much being done for them.

I see all these adverts for things like smart doorbells, smart fridges, smart kettles, smart this, smart that 'control everything from your phone' and do wonder what would happen if they all suddenly stopped working. Or even on a more basic level, what happens if your phone gets stolen or destroyed beyond repair? What do many people do then?

That said, Hawking has a point.
