^ sure is, even if made of plastics it can be detected.
The general question is do we want to live in a world with such stuff :hmmm:

Last i heard they are trying to program humans with an "elaborate" self-constructing biological "net" that is supposed to control the brain. Animal tests have already been "successful". I guess Philip Dick's Screamers were an optimistic view of the future. What a brave new world.

^ I think smartphones and social media serve the same purpose. Just days ago I saw another zombie staring at his cellphone while walking off the pedestrian'S pavement and onto the street and into the car traffic. To my great disappointment the car's bumpers stopped ten centimeters before the zombie's knee.

The driver was furious. The zombie kept on staring. I am in doubt that he even realised what almost happened.

The question implies that we have a choice in the matter. I don't think that is the case.
