How it's being sold, as a way to monitor high-stakes jobs like ATC or piloting, feels a bit like the "think of the children" excuse to dismantle encryption.

Maybe I've read Snow Crash too many times, but I can absolutely imagine some depraved industrialist using this as a means to track how much work their employees are engaging in. Worried that your HR flaks are mostly playing FB games? Strap them up with the "tat" and track their activity in real time.
