Connectionists: Stephen Hanson in conversation with Geoff Hinton

[Gary Marcus]

The whole point of the neurosymbolic approach is to develop systems that can accommodate both vectors and symbols, since neither on their own seems adequate.

If there are arguments against trying to do that, we would be interested.

The MCC comes to mind with Adm Bobby Inmann's  national US mandate to counter the Japanese so called"Fifth-generation AI systems"  as a massive failure of symbolic AI.

As the first national, large-scale artificial intelligence (AI) research and development (R&D) project to be free from military influence and corporate profit motives, the FGCS was open, international, and oriented around public goods.

Also it’ would be really instructive to compare with deep learning, which lost steam for quite some time, but reemerged much stronger than ever before. Might not the same happen with hybrid models?
