Belief in the Singularity and belief in God strike me as
extremely similar.
Both, I think, are extremely interesting ideas where very few theories, e.g. pro, anti, or anywhere in between, can be written off as ridiculous -- probably due to a lot of ambiguity and difficulty in defining proof.
For me, I find the Singularity very implausible due to the fact that we talk about "general intelligence" quite a bit, and the more we do, I'm finding that I don't think it exists. There are a set of low-level basic skills that I think -- if you don't have, you're not intelligent. And then there are higher level skills that vary wildly.
So, will we make AIs that can say and do very clever and amazing things; yes, this is happening. Will they be, like ascendant, or something? I would say -- yes, but perhaps not in the way we think? Like, humans made "The Bible." And that's obviously a big huge, impactful, maybe superhuman thing. But feels different from this idea of a "Singularity."
