Im sorry but if your arguments is that "AI is doomed because current LLMs are only good at fuzzy, probabilistic, outcomes", then you do not understand current AI or computer science or why computer scientists are impressed by modern AI.
Discrete concrete logic is what computers have always been good at. That is easy. What has been difficult, is finding a way for computers to address fuzzy, pattern matching, probabilistic problems. The fact that Neural Networks are good at those is precisely what has Computer Scientists excited about AI.
