Imagine you're a 12 year old in 2065 forced to wear a shocking device that forces you to "pay attention" in class but for whatever reason it incorrectly identifies you as never paying attention.

You could argue that it is poorly made but perhaps the model was trained in a rush because it was a cheap, knock-off produced en-masse for school-scale.

Even if its well-made; imagine you're some 1 in a 1,000,000 non-typical. Who is the school going to believe, some irksome child or the system that works perfectly fine for 99.99% of other students? "Obviously" in such a case, the child is lying and just needs to learn to pay attention.

Hopefully this will never be the case.

On the other hand it can be used to detect micro sleep in drivers and there it can save lives.

So yeah, as with any tech you can use it for good or bad and you should not use it for everything

I don't think it will solve the micro sleep problem because that's arguably more of a political issue than a technical one. The issue is rarely the drivers trying to drive till they drop but rather the businesses themselves trying to force the drivers to take on extra shifts (due to lack of drivers) or drive longer to deliver sooner rather than sleeping. In such cases in the future people will find a way to simply turn off the checks and still crash.

Regardless these long-haul issues should be resolved by automated driving anyway given that long highway journeys are a decent use-case for automation.
