I can imagine the first to be easier to switch to blocking AI progress once they feel the AGI than the latter as they don’t have rationalizations in place.
There’s also a third category, that of successionists which would ~likely change their minds if they had kids or if a lot of people dear to them had kids etc. as that (in my experience) moves your aliefs to “there’s something worth fighting for in humanity even if all current people are on average awful because the original state is so pure and full of potential for wonder and good things that a universe without this is one less valuable”
Thanks for laying this out, it was an interesting read.
On terminology, I’d prefer a term that is related to Knightian Uncertainty but isn’t the exact same as a similar but different thing from the one you’re talking about. I recommend Knighlingian as a Knightling is a smaller version of the Knight, or a Squireian if you can live with the pun.
