The internet is full of devices that should never have been connected to it. Refrigerators, baby monitors, and even toilets are all out there on the Internet of Things (IoT), many of them still with the factory preset password. Just because we can connect something to the internet, doesn’t mean that we should.

We most emphatically should connect things like this to the internet. It’s a remote-controlled rover, complete with a camera, that you can control from anywhere in the world over the internet – it’s a bit like one of Amazon’s smart doorbells, except that it’s got four wheels and you can use it to chase the dog around the house when you’re not in.
