I think the best way would have been to assume thought is wordless (as the science tells us now), and images and probability (as symbols) are still arbitrary. That was the threshold to cross. Neither neurosymbolic, nor neuromorphic get there. Nor will any "world model" achieve anything as models are arbitrary.

Using the cybernetic to information theory to cog science to comp sci lineage was an increasingly limited set of tools to employ for intelligence.

Cybernetics should have been ported expansively to neurosci, then neurobio, then something more expansive like eco psychology or coodination dynamics. Instead of expanding, comp sci became too reductive.

The idea a reductive system that anyone with a little math training could A/B test vast swaths of information gleaned from existing forms and unlock highly evolved processes like thinking, reasoning, action and define this as a path to intelligence is quite strange. It defies scientific analysis. Intelligence is incredibly dense in biology, a vastly hidden, parallel process in which one affinity being removed (like the emotions) and the intel vanished into zombiehood.

Had we looked at that evidence, we'd have understood that language/tokens/embedded space couldn't possibly be a composite for all that parallel.
