LLMs are a particular application of machine learning, and as such LLMs both benefit by and contribute to general machine learning techniques.
I agree that LLMs are not the AI we all imagine, but the fact that it broke a huge milestone is a big deal - natural language used to be one of the metrics of AGI!
I believe it is only a matter of time until we get to a multi-sensory self-modifying large models which can both understand and learn from all five of human senses, and maybe even some of the senses we have no access to.
