That last comment seems very far from the original post which claimed
We have no good reason, only faith and marketing, to believe that we will accomplish AGI by pursuing the DL based AI route.
If we don’t have a biological representation of how BNNs can represent and perform symbolic representation, why do we have reason to believe that we know ANNs can’t?
Without an ability to point to the difference, this isn’t anything close to a reductio, it’s just saying “yeah I don’t buy it dude, I don’t reckon AI will be that good”
Sorry I think you are misunderstanding the reductio argument. That argument simply undermines the claim that natural language is not based on a generative phrase structure grammar. That is, that non symbolic DL is the “proper” model of language. In fact they are called “language models”. I claim they are not models of language, and therefore there is no reason to discard symbolic models … which is where the need for symbol manipulation comes from. Hence a very different sort of architecture than current DL
And of course we can point to the difference between artificial and biological networks. I didn’t because there are too many! One of the big ones is back propagation. THE major reason we have ANNs in the first place, completely implausible biologically. No back propagation in the brain.
