Making FR more 'perfect' will also allow the less desirable regimes to go after their dissidents in a more 'perfect' way, there are some historic implications that might have changed the balance completely. Now, of course there is such a thing as the distinction between the tool (say, a hammer) and its use (say, hammering a nail in), and the alternative uses that those tools are being used for.

The people at Google and Facebook are slowly figuring out that their data driven perfect future may not be one that they themselves (or their descendants) would like to live in. Face recognition for computers enables a whole pile of use cases that are downright scary and I would love for such tech to be stalled as long as possible.
