Theories of consciousness will lead to actionable understanding of AI consciousness²
Global workspace theory makes anthropic's discovery of the "j-space" much more plausibly a sign of AI consciousness. If a theory of consciousness doesn't help us determine between whether AI is conscious or not, I don't think it's much better than a theory of phlogiston is to fire.
I would also add to point 3: don't go "whale fishing" and search in ways that generates a ton of "bycatch" (excuse the fishing analogies, it's too useful to not use for this point but irl leave the fish alone). Putting out huge calls saying "we need all hands on deck, we're heavily talent constrained and can't find people, you should apply even if you don't think you're a good fit" is going to reach a ton of people who really are not a good fit, who will think this is a worthwhile pivot because they are talented and the field is talent constrained, and waste a bunch of time applying and considering ways to orient their life to the new direction. Then when they inevitably are not a good fit, and talent constrained means something along the lines of "we're having trouble hiring the top 99.9% talent" and not "we're having trouble hiring the top 80% talent", they will get more bitter and cynical about the movement and doing good effectively, and may even miss opportunities that would be a good fit.
