Yes, they tend to be pretty good at pattern recognition, which has enormously useful applications in manufacturing, data sorting, translation, and more. There are absolutely use cases for AI/LLMs. The problem is that, under capitalism, LLMs are being overhyped as a new market for finance capital to saturate (creating a bubble), and that these huge, inefficient data centers are being pushed as ultimate investment vehicles at the immense destruction of the environment. In a socialist economy, with strong guardrails on the development of LLMs, these can be made to help society in general. See how it's treated in China vs. the US Empire.

AI/LLMs are not a panacea, despite what investors will try to tell you. At the same time, they are not utterly worthless. They have definite use cases that will be found gradually.
