Do you think that the Islamic State is an entity which will vanish in the future or not?

Nothing lasts forever, though religions (in a fairly general sense) last longer than most things.

To my mind, the interesting question is whether the Islamic State will be gone soonish. In the short run, it's anti-fragile. It feeds on being attacked. On the other hand, it revolts every other institution which has a preference for normal human life.

It's possible that the rest of the world will solve coordination problems so as to destroy IS by military attacks.

I like the idea that it will take inspiration-- the development of a new religion or variant of Islam or alternatively some brilliant satire-- to create something to move people away from IS. It's pretty clear that mere decency isn't motivating enough.

Do you think that their particularly violent brand of jihadism is a worse menace to the sanity waterline than say, other kind of religious movements, past or present?

I have no idea. I wasn't there for the other religions.

Do you buy the idea that fundamentalism can be coupled with technological advancement, so that the future will presents us with Islamic AI's?

I don't think fundamentalists are good at innovation (have I missed something?), but they're at least as good as everyone else at using innovations invented by other people. They may be better at it if they're more motivated.

If there are AIs without a FOOM, there will be Islamic AIs, which is not the same thing as jihadist AIs. I think we can expect AIs from all the major religions and subdivisions of religions. If AIs are cheap (and I haven't seen speculation on what AIs will cost), there will be AIs based on fringe and new religions as well.
