I would argue that, unless you can show why AGI is not - in principle - possible, that the null hypothesis would be that it is possible. Unless we veer off into some weird mysticism, it seems that the human brain turns energy and matter into intelligence somehow, operating according to the physical laws of the universe... why shouldn't it be possible to build something else that does the same?

If you're unwilling to provide me with a prototype equivalent to a rodent mind then I'll settle for a fully developed theory of human cognition. Let me know when you've got one. At least that would give researchers some guidelines to know whether they're making forward progress toward AGI.

Yeah and before the measurements were done, before enough time had elapsed for meaningful change to be measured, all there was was people like me screaming at people like you, trying to make you see. When ai comes you’ll have your proof but it will be too late.
