Maybe the result of one person’s clones forming a very capable Em Collective would still be suboptimal and undemocratic from the perspective of the rest of humanity, but it wouldn’t kill everyone, and I think wouldn’t lead to especially bad outcomes if you start from the right person.
I think the risk of a homogeneous collective of many instances of a single person’s consciousness is more serious than “suboptimal and undemocratic” suggests. Even assuming you could find a perfectly well-intentioned person to clone, identical minds share the same blindspots and biases. Without diversity of perspective, even earnestly benevolent ideas could—and I imagine would—lead to unintented catastrophe.
I also wonder how you would identify the right person, as I can’t think of anyone I would trust with that degree of power.
No, I don’t think anyone could, barring the highly unlikely case of a superintelligence perfectly aligned with human values (and even still, maybe not—human values are inconsistent and contradictory.) Also, I think a system of democratically constructed values would probably be at odds with rational insight, unfortunately.
Regarding the rest, agreed. Heading into verbotten-ish political territory here, but see also Jenny Holzer and Chomsky on this.
