1. Please add the 'open_thread' tag.
2. Check if there is an active Open Thread before posting a new one. (Immediately before; refresh the list-of-threads page before posting.)
3. Open Threads should be posted in Discussion, and not Main.
4. Open Threads should start on Monday, and end on Sunday.
Most of the arguments I've seen against AI risk I've seen (in popular media, that is) take the form of arguments against AGI, full-stop. Naturally there exist more nuanced arguments (though personally I've yet to see any I find convincing), but I was referring to the arguments made by a specific part of the population, i.e. "people who engage in such goalpost-moving"--and in my (admittedly limited) experience, those sorts of people don't usually put forth very deep arguments.
Here's some arguments against AI x-risk positions from an expert source rather than the popular media:

In any case I think you have unnecessarily limited yourself to considering viewpoints expressed in media that tend to act as echo chambers. It's not very interesting or relevant what a bunch of talking heads say with respect to a technical question.
