The more intelligence augmentation is equitably spread the more likely that there will be less consequence free power over others.

That is not apparent to me though. It seems like it would lead to a MAD style situation where no agent is able to take any action that might be construed as malintent without being punished. Every agent would have to be suspicious of the motives of every other agent since advanced agents may do a very good job of hiding their own malintent, making any coordinated development very difficult. Some agents might reason that it is better to risk a chance of destruction for the chance of forming a singleton.

It seems to me very hard to reason about the behaviour of advanced agents without ultimately resorting to mathematics ( e.g. situations involving mutual-policing should be formalizable in game-theoretic terms ).
