You guys really need to look into what's been going on in classical AI in the last 20-30 years. There are two large conferences that are mainly about symbolic AI, IJCAI and AAAI. Then there's all the individual conferences on the above sub-fields, like the International Conference on Automated Planning and Scheduling (ICAPS). Don't expect to hear about symbolic AI on social media or press releases from Alpha and Meta, but there's plenty of material online if you're interested.
