I remember when IoT was getting big. They talked about how one day, hackers might be able to take over your Nest or other smart thermostat and set the temp to 90-something degrees until you paid them. I laughed at that. I also remember when a bunch of refrigerators died or something because the screen used a software that was deprecated. I would be pretty upset to pay all that money for a fridge just to have it die on me in such a manner.
