Mostly the folks at HLAI are not EA aligned and those that are EAs are not necessarily act utilitarians. I think EA is a lot bigger than act utilitarianism these days (if it wasn’t I wouldn’t think of myself as part of EA!), and the main way EA is interacting with these folks is through doing things to move beneficial AGI within the Overton window. That said there is some notable overlap (there are at least 2 EAs on the beneficial AI panel and maybe more closeted ones).
