We need to block it on a federal level in the USA. Don't allow any state to use facial recognition software for any reason, except maybe at airports, but only for terrorism---not for any other reason.
That little loophole right there would soon be big enough to let through a freight train.
Our politicians might be convinced to introduce token pieces of legislation that can conveniently be voted down by the other side, and just enough of their fellow party members. But that's about it.
The US change from a fixed 28 year term that could be renewed once to a life of author + 50 years term was done to match the minimum term allowed under the Berne Convention, which most of the world had already done decades before.
In 1998 the US lengthened the term again, to life + 70 years. That one was to match Europe, which had made that change in 1993.
We don't need to block it. We need to embrace it and make sure it's used properly, safely and with accountability. We're not talking about nuclear warheads here. There has to be a safe and secure way to get the benefits of large-scale and centralized facial-recognition and tracking.
True, we're talking about something worse. The danger is higher and the detectability and barriers to entry are lower.
This has never worked, period.
No, we're not. Those damage the physical world. Facial recognition will damage something else in the long run - the society - which is just as dangerous.
After that what benefits are there for creating a database with everyone historical location?
