Well, I guess we're just naturally evolving and adapting into enslaving ourselves, just following nature's course... There doesn't need to be a "master plan", but clearly there are some working themes
Remember the experiments with rats and pigeons that could administer hits of plesure giving drugs? They all hit that button til they died. We are no different.
Even then, sure. there have been extreme examples of such things like a few korean individuals dying in their rooms playing MMOs, not even taking enough care to feed themselves.
