Spying technology should not be considered immoral because of the “private” kind of information that it captures, but rather because it violates reasonable expectations about the use of the space in which it is deployed. For better and for worse, those expectations are about to change rapidly and permanently. Miniaturization and mass-production of sensor and storage technology will soon allow anyone to set up hidden audiovideo surveillance of almost any location to which they ever have physical access.
If you don’t want certain information about you to spread, then don’t emit it.
And if you don’t want an innovation of yours to spread, then don’t share it with anyone unless you’ve arranged enough bonding/insurance for the case of it escaping into the wild.
