I've entertained the possibility that we might discover that "feelings" and language communication are emergent properties of statistical possibly partly stochastic nets similar to LLM's, and that the next tough scientific and engineering nut to crack is integrating multiple different models together into a larger whole, like logical deduction, logical inference and LLM's. LLM's are undoubtedly an NLP breakthrough, but I have difficulty imagining how its architecture can from using first principles as the training corpus derive troubleshooting steps to diagnose and repair an internal combustion engine, for example.
