Ask HN: What are the hottest areas of *non*-LLM AI work currently?

10+ years ago, "AI" would likely refer to work in RL, evolutionary/genetic algorithms, etc.

Nowadays most of the spotlight seems centered on LLMs, CNNs, and other methods that are either human-labeled or at least reliant on human-created data, and have a static separation between "learning" and "inference".

I know that there are still non-LLM, non-CNN, non-anthropocentric topics of AI development currently, in RL and in other areas. Which would you say are the most prominent or promising today, or likeliest to come to fruition?
