> Imagine it's 1995. The Web gets banned for five years so that a government committee can meet to figure out what could possibly go wrong with that technology.

Fortunately we already know what can go wrong with facial recognition technology. We have China, and we have American and Israeli and various Asian marketing startups inventing abuse after abuse after abuse. So there is already a test bed in place; it doesn't have to be the entire world.

As a general principle, it may not be a bad idea itself. Let a part of the world play with the new toys and other part observe, after that either the tech will be exported to holdouts (the control group, if you like), or the regulations will be exported to the experimenters.
