I predict we'll soon have virtual USB keyboards provided by a Raspberry PI with an open source "productivity simulation" software running. If companies want people to score highly on activity metrics, some workers will do just that: Score highly on the metrics.

I mean for some jobs, work has been mostly performative for quite a while anyway, so then this is the logical next step.

Slightly unrelated: I'd also love an app that modifies my webcam stream so that I'm always staring at the camera. That way, I can read blogs and nobody will notice.
