Drawn to the Nest

Nest Labs has introduced a new home-security camera that will

take facial recognition to another level, with better sensors and software smart enough to detect the difference between family members, pets and potential intruders in the home.

Your humble blogger is enamored by shiny gadgets, but he is very wary of devices that are part of "the Internet of things" and can readily be hacked.

Even if they are reasonably secure, the devices are smarter than he is, can learn faster than he can, have detailed knowledge--e.g., medical and financial--about everyone in the household, and can recognize everyone by sight.

What could go wrong?
