I believe a neuro-symbolic approach is the only way to realize truthworthy reasoning, thus achieving true intelligence. It is probably the only hope to bridge the seemingly insurmountable gap between “correlation” and “causality”.
Here are some useful cases of the neural symbolic approach. And by now neuro-symbolic reasoning has become mainstream. Here is a podcast where I talked about AI reasoning.
Synthesizing high-quality, verifiably correct reasoning steps on solving math problems. (Li et al., 2024).
Improving the autoformalization, a fundamental math capability of a neural model, through a hybrid neural-symbolic solution. (Li et al., 2024).
Proving Olympiad inequalities through neuro-symbolic formal reasoning. (Li et al., 2025)
