You haven't thought much about the risk of superintelligence if you think it is a typical risk. Is that compared to poorly designed children's toys or nuclear weapons?

I would go as far as to say, "humanity" as it is defined today, is doomed, it is just a matter of time.

The only question is: Will doom play out with a dramatic disaster or as a peaceful handoff/conversion from biologically natural humans to self-designed intelligence.

Either way, natural human beings will not remain dominant in a world where self-interested agents grow smarter in technologic instead of geologic timescales.
