Suppose, as this argues, that effective monopoly on AGI is a necessary factor in AI risk. Then effective anti-monopoly mechanisms (maybe similar to anti-trust?) would be significant mitigators of AI risk.
The AGI equivalent of cartels could contribute to risk as well, so the anti-monopoly mechanisms would have to deal with that as well. Lacking some dominant institutions to enforce cartel agreements, however, it should be easier to handle cartels than monopolies.
Aside from the “foom” story, what are the arguments that we are at risk of an effective monopoly on AGI?
And what are the arguments that large numbers of AGIs of roughly equal power still represent a risk comparable to a single monopoly AGI?
