The microchip actually "listens" to brain cells as you can read below:
CBC News - Technology & Science - Calgary microchip 'talks' to brain cells
So where do you see technology like this going? To help sufferers of disease? To tell police when someone is about to commit a criminal act (a whole new kind of supervised release)? To test for undesirable thought patterns in the populace (kinkiness*, anti-social thoughts**, wanting to vote against the Supreme Leader)?
How should the potential benefits of a technology be measured against possible abuses of the same technology?
*kinkiness is always acceptable here.
**I'm sure theocracies would line up to buy the "A" chip to root out unbelievers in their midst. (In Canada it would be the "Eh" chip).
