That's assuming they clear several hurdles and their little nightmare system works out to be the dream they want for them.
It won't. It'll be a dystopian nightmare for them too.
They always fuck up their goals and only end up closer by the sheer inertia and risk insulation that controlling our economic output gives them.
Then some bright and talented person who dreams of doing the right thing provides the missing links in their machinations and they either steal or buy them.
They made sure that wouldn't happen this time by preemptively trying to rob all of the brightness until those who can won't give them anymore, and those who will are slowly being cognitively robbed of the capability itself.
The AI taking over is both (as currently deployed) impossible and probably amongst the best outcomes, compared to the deathly wave of fucking ineptitude these chuds are unleashing and will continue to unleash.
