I think in the future everyone will wear masks like daft punk

It won’t work alone for long in the age of AI. You won’t be tracked and identified by face alone. It’ll be a complex array of data points. Your face, your hair, your eye color if the cameras have the resolution, your height, your gait, your posture, your scars and injuries, your visible birth defects, whether you use mobility aids, the wireless devices emitting signals in your pockets, the list goes on and on. They’ll assemble dozens of data points and make it extremely difficult to falsify enough to avoid detection instead of just getting flagged as suspicious.

Will they actually devote the resources to try to pierce the anonymity of those handful of people? Everything we’ve seen about how tech companies operate is that they reach a threshold of “good enough for most cases” and don’t bother trying to optimize the edge cases. Collecting the billions of data points to try to use dozens of analysis techniques, and then having some kind of meta analysis on how to resolve disagreements between models, would be resource intensive beyond their own profit motives.

Someone who wants to defeat gait analysis with a different pair of shoes (heel height and sole thickness and back support affect how people walk), and wears a mask might lose the arms race if the tech companies choose to continue to improve the tech even after it’s already good enough.

I think it’s possible but not inevitable. Especially if there’s a financial reckoning for AI companies soon.

Will they actually devote the resources to try to pierce the anonymity of those handful of people?

Given how rapidly they’ve been trying to tighten their grip lately? Yes. They want to know everything about everyone all the time. And they don’t give two shits if we consent to it.
