The “Internet of things” (IoT), being the future paradise that awaits us
when all of our devices are connected to the net, is a worrisome prospect
to just about anybody who has thought about its security and privacy
implications. It would be problematic even if the design of all connected
devices included security and privacy as absolute requirements — but that
is not the way these devices are made. Currently, it is possible to opt
out of much of the IoT experience with a bit of attention and discipline.
In the near future, though, that situation is likely to change and it is
not clear what we can do about it.
