A point being moot is a reason to agree to disagree, if they can't agree on the premise. But they need to say that. If I were writing a letter, I would say it because that's just being sensible. This isn't about logical debate. This is about reasonable, non-sophistic writing at the college level or higher. And there are basic standards, like if they don't know the future then they must explicitly acknowledge that. Not rhetorically "do that" in the essay. Literally write it out in sentences. They didn't. I can think of 3 examples where such explicitness was done. Chomsky's letter gave explicit reasons why AGI is a false issue (and he was pilloried for it). My computer science professors literally, in their deep learning class and in their theoretical machine learning research seminars, have literally acknowledge that we don't know almost anything about the fundamentals nor the future. That scientific humility and level of intellectual conscientiousness is needed. That is absent in this discourse between the experts. And note, by that, I also include the 22-word "letter" which doesn't actually explain why Hinton and the rest of the signatories think AGI is an existential risk, what their specific reasons (your "material evidence") for that are.
