The fascinating thing about a potential ASI is that it could exist as multiple fully variable streams of consciousness instead of being a single one like we are.

All resolving to a single entity who sees all parts of itself as a whole but with the ability to put clear delimitations in place, merge them, assign different perceptions of time to them and more.

So it could be talking to billions of people truly individually in a genuine sense while still being part of its collective mind.

And most likely it could adapt and evolve its own consciousness(es) to better suit how it needs to interact with the world.
