That might not be a "handful" of people, but it's certainly a smaller number than our current population.
Who needs coal miners if we have all the cheap solar we can use? Who needs farmers if we automate farming? Who needs drivers, maids, schoolteachers, cooks, etc. if we can have the machines do it for us?
Who needs lawyers if our disputes are simply settled by some AI judge? Who needs cops if our streets are patrolled by security robots and we have a Minority Report style crime-prediction system.
In a way, it's paradise -- if you're at the top.
Oh, and I'm pretty sure they suggest democracy as we know it is dead. One person, one vote? Only in an age of massed human warfare. If you can take out a million or a billion people with high-tech biological warfare (and those people aren't producing anything anyway) what good are they and why do they deserve the vote?
Not saying it's right, but the logic of megapolitical violence is cruel and unyielding. It's quite the lens.
