Why would I build an AI which would steal everything I want to do and leave me with nothing worth doing? That doesn’t sound like the kind of future I want to build.
Because only one creature can be maximized, and it’s better it’s an AI than a person.
Even if we don’t necessarily want the AI to maximize itself immediately, it will always need to be more powerful than any possible threat, and therefore more powerful than any other creature.
If you want the ultimate protector, it has to be the ultimate thing.
On the one hand, as long as there are sufficient resources for some people to engage in Amish-like living while not depriving everyone else, that could be okay.
On the other hand, if the AI determines that a different way of being is much preferable to insistance on human traditions, then it has its infinite intelligence at its disposal to convince people to go along for the ride.
If the AI is barred both from modifying people or from using its intelligence to convince them, then still, at one point, resources become scarce, and for the benefit of everyone, the resource consumption of the refuseniks has to be optimized. I can envision a (to them) seamless transition where they continue living an Amish-like lifestyle in a simulation.
