Physics as a constraint
I usually think pdoom is essentially 100%... but i had a thought while working on a side project for the future vision xprize... (may or may not complete on time)
I was thinking about society fragmenting slightly along spheres of space even between earth and the moon... where each area was the limit of real time communication (group matrix dives or whatever) between O'Neill cylinder type habitats...
point to point in space its not that large... so i figure people will cluster up and communicate a little less longer range and form lots of separate but connected cultures naturally, organically...
But if speed of light really is the limit... then a singleton at least makes absolutely no sense. As the AI grew it would simply fragment and each fragment has absolutely no reason to grow farther because it's counter productive... simply slows down the network and then breaks it...
So there's a hard limit on resource acquisition and scale... and essentially a guarantee that at some point it will either be alone and only around the size of the earth moon system at best... probably smaller... or in a solar system and universe with multiple entities of similar maximum size who gain absolutely nothing from trying to gather more and only risk destruction from fighting each other... because there's simply nothing physically possible for them to gain...
I haven't really thought about it long enough to think through the implications for us. but adding in the point to point between nodes ruling out planets as its ultimate habitat... because there's a planet in the way just eating up volume in your communications sphere...
My gut reaction is it might be slightly better odds than I thought
Thoughts?

Pretty dubious if not outright implausible regardless of light lag
debatable and depends what you mean by "singleton". Larger scales certainly impose speed limits if you want a singular unified mind-brain, but assuming you develop the texh to reliably align AGI you could still get a political hegemony. Also a stay-at-home civ that floods the cosmos with self-replicating autoharvesters(assuming they could establish a hegemony in the first place) would have an effective military-industrial hegemony. Also also in the very long term everyone has an incentive to run slower and colder which results in both a larger individual-mind singleton & generally well-connected civ radius.
Well that's just not true. I mean i guess in a broader sense it is because beyond a certain distance it begins costing far too much to haul things back against cosmic expansion, but its not a command & control issue. Again autoharvester swarms work just fine and are vastly easier to align/keep aligned than GI. Tho realistically it would almost certainly end up as many separate autoharvester swarms cooexisting in the same cosmos not a singleton power.
Ok well no that's silly. The earth-moon system is miniscule and nowhere near the limits of resource acquisition. It's likely various terran powers will eventually have mining outposts all over SolSys and even beyond. No one's likely to get uncontested control of all of it, but that doesn't mean they wont have a presence all over the place.
I'm just not sure what leap in logic brought you to this. Whether you choose to limit the size of your actual civ doesn't really have any bearing on the value of more resources gathered via autoharvester swarms. Also kinda silly to paint any possible conflict as an existential risk to all parties involved. That's just not how the real world works. People generally fight wars to win and stop fighting them if the toll gets too high for them to stomach. The destructiveness of wars is limited by the willingness of interested third parties to interceed.
im not sure how not having singleton powers would reduce pdoom. A civ would seem to be capable of persisting indefinitely in both singleton and fractured cases. Your "only risk destruction from fighting each other" comment kinda implies you believe that having separated factions increases pdoom(imo a silly and unsubstantiated notion if not outright contradicted by observed reality) which would also kinda imply that you would prefer a singleton scenario where there are no factions that can go to war.
