I have the impression that neither “short” nor “medium”-termist EAs (insofar as those are the labels they use for themselves) care much about 100 years from now. With ~30-50 years being what seems what the typical “medium”-termist EA cares about. So if you care about 100 years, and take “weird” ideas seriously, I think at least I would consider that long-termist. But it has been a while since I’ve consistently read the EA forum.
