About how 1980s logic-based AI like Prolog compares with today's LLMs.

Pretty amusing the old AI revolution was pure logic/reasoning/inference based. People knew to be a believable AI the system needed some level of believable reasoning and logic capabilities, but nobody wanted to decompose a business problem into disjunctive logic statements, and any additional logic can have implications across the whole universe of other logic making it hard to predict and maintain.

LLMs brought this new revolution where it's not immediately obvious you're chatting with a machine, but, just like most humans, they still severely lack the ability to decompose unstructured data into logic statements and prove anything out. It would be amazing if they could write some datalog or prolog to approximate more complex neural-network-based understanding of some problem, as logic based systems are more explainable

An LLM writes Datalog or Prolog that captures its understanding of a complex problem as explainable logic.
