In the case of smart devices in your home we do still have a choice -- just don't buy them or use them, or ensure that the ones you do use have strong protections, etc. However with DNA it is like you are screaming it in countless public places daily and it was only ignorance that protected its privacy. That time is rapidly coming to a close. The cost and time of processing it, once prohibited, has fallen through the floor and soon enough just doing mass dragnets is going to be trivial. It seems likely that generating facial profiles from DNA is not too far off either. Couple that with a facial recognition system and you have a deep identity.

We should fight it as possible, but we'll see how far that gets us.
