Slightly odd other idea: some new AI technology is developed, massive leaps are made. Everything seems great until the AI start developing in odd, sometimes psychotic ways. Turns out the 'Artificial' Intelligences were originally humans, with parts of their brain slowly replaced with electronic alternatives until no meat was left. Because the process has to copy the original subject's brain so closely to work, some human characteristics are copied over and can emerge as the system matures. It turns out the original experiments were violent prisoners, and more recent, 'stable' ones were done on small children. Cue ethical catastrophe.

So.. basically... the backstory behind Portal?

Dystopian society. A new, incredibly accurate set of psychometric tests (something like IQ/MBTI on steroids) is discovered, and society as we know it is restructured into a kind of pre-emptive meritocracy. Perhaps even a different angle where the people tested are prisoners of some 'free' society and are used for its advancement.

Because of course everything has to be a bloody dystopia nowadays.
