I am so glad I found this video. The presenter gives rise to various useful points!

I was there, and after 8 months I am still studying what he said...

It seems to me like there should be a way to run proof searches where you are constrained to converge to logical proofs but you allow a pre-trained intuitive neural network to make the decisions about which paths to explore first.

Another idea is some non-symmetric adversarial system where one half of the system is optimizing to imitate human creativity and the other system is optimizing for logical correctness. A left brain/right brain system.

What is the main argument professor Bengio has against hybrid systems (DL + Symbolic AI)?

Thank you very much Professor for a so bright talk.
Just a question : the System 2 Deep Learning architecture showed is very similar to the Bayesian network Open-universe Probability Model - OUPM (section 14.6.3 of the book of Russell and Norvig: Artificial Intelligence, a modern approach). Is possible to elaborate about the difference, please?

Dual-system theories are popular in psychology but highly disputed. Kahneman may have received recognition for research related to System 1 (heuristics and habitual responses). What is disputed, however, is System 2. Is a System 2 necessary to explain human "higher" cognition. It is probably a bad idea to base your AI ideas on this flawed idea from psychology.
