None of those obviously mean the same thing (“runaway AI” might sort of gesture at it, but it’s still pretty ambiguous). Intelligence explosion is the thing it’s pointing at, though I think there are still a bunch of conflated connotations that don’t necessarily make sense as a single package.
I think “hard takeoff” is better if you’re talking about the high-level “thing that might happen”, and “recursive self improvement” is much clearer if you’re talking about the usually-implied mechanism by which you expect hard takeoff.
