It's very likely that many or all AGI researchers...very unlikely that they will...

If I had an extraordinary idea related to a field of expertise that I am not part of, I would humbly request some of the experts to review it, before claiming that I know something that they don't know, if I don't even know if my idea makes sense.

Has this happened? All I know about are derogatory comments about mainstream AGI research, the academia and peer-review in general.

In case it has happened, it seems that the idea was not received positively. Does that mean that the idea is bogus? No. Does that mean that you should be particularly confident in your idea? No. It means that you should reassess it and gather or wait for more evidence before telling everyone that the world is going to end, create a whole movement around it, ask for money and advice people to neglect any other ideas, because everyone else is below your epistemic level.

Why do these discussions constantly come down to the same people debating the same points?

Because nobody other than a school dropout like me cares to take a critical look at those points, points that haven't been addressed enough to generate the slightest academic interest.
