A lot of the curtailment of civil liberties in recent years would have been preposterous a decade or so before they occurred.

You still have free will, but your ability to act on it can be constrained as far as it relies on the use of technology.

I agree with the article in that such things will be cracked, at least initially. But these processes do get better iteratively.
