P(Doom) is literally naming probability of something
Literally naming the probability of something is not the optimal thing for P(Doom) to mean. It is better for it to be a number between −1 and 1 which represents the badness of AI, overall, because that is the thing that people actually want and that is in practice how they use it.
So I have developed the meme of negative P(Doom), e.g. if you think that P(Doom) without AI is 90%, but 5% with AI, then P(Doom) is −85% (negative 85%)
If you limit P(Doom) to being positive, that makes it literally impossible to express the view that AI is actually good in the framework that people are trying to popularize by asking everyone for their P(Doom) but not asking them to also give their P(Doom|~AI)
