Ok, this is pretty cool. I've been following this technology for 20 years.
Electronic tattoos that read your mind.
Seriously cool, and scary, stuff.
So here's the problem I see. This is nearly invisible technology that potentially has the capability to read your mind, physical state, become a cell phone etc. So theoretically you could slap one of these on someone without their knowledge and know everything about them pretty darn quickly. I can see this destroying the concept of privacy as I can't really envision any defence against it.
On the bright side, you could effectively work on anything you like anywhere, anytime, hands free. No more carrying your cell phone/laptop around, eventually no more wallet I expect. Since the idea of privacy will eventually just disappear since it can't be enforced we're all going to be come tattoo'd nudist hippies that work from the beach.
