I am equally surprised by the comments about how come engineers implement such systems, how they find it ethical, etc. I'm sorry, but it sounds just a bit out of touch with the real world, or just outside of HN bubble. Given the things that money motivates people to do, it's probably one of the least unethical things that has been done.
I am not judging that this is right or wrong, I am simply stating the fact that nothing about this should be surprising. Yes, this is slightly sad, but that's simply the reality of technological advancement. It's not really possible to expect the rest of the world to use the technology only for things considered 'right', etc.
OTOH, what is so interesting in simple face recognition, innit? That future became a past quite fast, meanwhile teh human rights never get old. (smile.jpg)
A while back I had a plan for a science fiction setting: an intergalactic ship is approach Earth. The people who sent it thought big, and as a result the ship has at its core an enclosed star (a miniature Dyson Sphere) as a gravitational anchor and power source, and round it is orbiting a vast swarm of asteroids and habitats with a few million times the living space of Earth, inside which civilisations endlessly rise and fall.
The plot centred around this thing going to make a class pass by Sol in a few years at 0.01c, with the gravitational effects pretty much dooming the Earth; so the current lead civilisation sends some ships on ahead to evacuate the Earth. (Big ships. I did the maths.)
The story never gelled, but I think it's plausible that my ship would produce these effects.
BTW, if this turns out to be true, I want credit.
Terre en fuite (Fleeing Earth) (1960) by François Bordes (pen name Francis Carsac), though, there is still no translation in english of that gem, where Earth and Venus was converted to spaceships for running away from exploding Sun!
I can even recommend it even if you never experienced burnouts, PA's.
