Taking your estimate as a superlative, it would be asinine for the community here to censor AI-targeted discussions in the way I think you'd like to. The same goes for a programming community that censors discussions about LLM programming.

You are basically asking for a brain drain in a field that—like it or not—is going to be crucial in the future in spite of its obvious warts and poor implementation in the present. If that's what you want, be my guest and encourage it; but who's authorized to unilaterally make that decision in a given forum?

In the present case, the moderators for r/programming are. But they're making a mistake by marginalizing the technology that's redefining the practice because people talk about it too much instead of thinking about how to effectively talk about it and then steering the community in that direction.

But that's a full-time job. Which is why I think HN may turn out alright in the long run or a similar community will replace it if it fails to temper the change in the industry.

What this decisions signals to me is that r/programming has been inert for some time. I'm sure plenty of programmers, irrespective of their position on AI, probably find the community rejoicing in their resignation to the technologies influence as their cue to finally exit.
