Most likely wrong if you compare to how most other development in engineering happened.
From my point of view, the most likely path towards some form of weakly general intelligence at this point is emergence. We keep working on these narrow problems and from the broadening networks at some point we end up with something indistinguishable from a general ai inadvertently.
Planes don’t fly like birds. There is very little reason for what you would call a “general intelligence” ai to develop in a way which mimics our own intelligence. It might but I would find that more notable that if it did not.
I'm fairly certain you cannot rigourously define "proper true AI", and I'm also fairly certain you don't mechanistically understand how humans think. This raises the question: where does your confidence that our current path is not pretty close to "proper true AI" and/or how humans think come from?
Machine learning models have written multiple scholarly papers that have been accepted to prestigious journals. Find me a rabbit that did that.
