You just attach a chip to any object like that kiddy proof circuit board mounted on top of that car and voila you can collect data on motion, temperature, facial recognition, lights etc. anything to do with perceptual and cognitive features controlled from an online or local connection. Could we attach it to humans?
From the movie "Falling Skies" alien harnesses. With nanotechnology it would be possible to regulate and collect data on anything embedded in a cell to mere electrical synapses. Yes it may help collect data and control and regulate heart conditions, blood flow, inflammation to just speeding up healing properties. That would be amazing. But what if the same can be hijacked to make someone bleed to death. A hacker could kill someone with this technology.
