Many people hold up 'AI As Normal Technology' as a reasonable "normal-people" or "economics" case against the doomer position. I actually think it's wrong on a number of ways and falls flat on its own terms. I think I believe this for reasons mostly orthogonal to being a doomer (except inasomuch as being a doomer makes me more interested in thinking about AI). If anybody here is interested in fighting the good fight, it might be valuable to do a Andy Masley-style annilihation of the AI As Normal Technology position, trying to stick to minimally controversial arguments and just destroying their arguments with reference to obvious empirical and logical arguments. I suspect it won't be very hard. Eg here's a few obvious reasons they fail:
Overall I think it’s a deeply unserious form of futurism, only held up by Serious Policy People who want to believe in a pre-determined comfortable conclusion.
Should be fun to take down for any of my friends who are bored undergraduates or graduate students interested in destroying bad arguments. Could be a easy way to get a bunch of views on a moderately important topic.
Considering that the skeptics in the example you've outlined are mostly misinformed/uninformed due to misconceptions about AI, I find that skepticism is more of a natural response to uncomfortable assertions made by AI boosters ("It's coming for you!") than a fault in epistemology in the search for truth. It makes the most sense to me that the default position skeptics take is anti-AI, but with any suggestion that the technology is unable to improve, their position becomes that of a skeptic. For this reason I believe it'll be difficult to convince skeptics with logical arguments before there's clear evidence against their point, mostly because of their strong bias.
