I remember reading several years ago that one of the theories about the Christian Apocalypse had to do with AI/appliances rebelling against us. Eventhough I'm an atheist, this scenario actually concerns me with all the smart appliances getting smarter and the ability to easily hack them.

Is this what happened with the processed toaster, LOL.

I don't think it a dangerous to have appliances on the Internet but I feel there's no need to put most of your appliances on the Internet. I recently installed an 8 camera surveillance system and it is connected to the Internet it's very handy for watching my house I spending his winter in Summerland key Florida and I can check my house daily to make sure the furnace is work. Also can check the inside rooms and outside the house that everything is OK , I'm very happy with the system.
