This is a good example, why not all devices should be connected to foreign servers. Errors can happen everywhere. But it could end badly, if some Corporations make errors and creating trouble, which would otherwise not happen.
In the case of the 3D-printer it is not that bad (except it destroys itself or even gets on fire), also you can turn it off. But imagine a smart stove top that lights up a towel (or something similar) while nobody is home.
Not, that I think that it is not useful to have something like that, but wouldn’t it be nice, if that stuff would work locally? (with the WireGuard integration in modems, the access from outside of home with the smartphone, should also be no problem for non-tech people)
Recently at work they replaced the AEDs with new models that support Children, and have a Spanish guide mode, super nice. But they also are now connected to the Internet so that they report any usage and order a new set of pads automatically, plus it has a bright screen constantly cycling through advertisement of what the device is. Also for some reason the power button isn’t actually a power button, and just triggers the start-up process while calling back to base, just like touching the on-screen buttons or pulling out the pads will do.
What could go wrong?
