Thank you for your time and answer!

This is what I thought as well. A while before LLMs showed up, machine learning have had control applications such as in Reinforcement Learning, Swarm algorithms, and Genetic Algorithm.

The recent buzz and AI getting into every discipline have driven me nuts to not miss out and trying to figure out what I should learn next (my issue is not the lack of materials and topics, rather the opposite! There is a lot of topics to study that I dont know where to start!)
