I divide anti-AI people into two groups. Those who don’t like AI because of what it is, and those who don’t like it because of its impact on society. Naturally there is an overlap.
Luddites were not opposed to the technology. So the comparison to them is only correct for the latter group.
Not talking about LLMs on a forum is not going to change anything in the grand scheme of things. It could be a protest, but I see it more (the feeling I get from the announcement) as a means to protect the forum from being overrun regardless whether AI is ultimately good or bad.
Also note that nowhere in my comment I have stated my position in this argument.
