It's not "good enough", it's mostly overhyped marketing garbage. LLM models are mostly as good as they're going to get. It's a limitation of the technology. It's impressive at what has been done, but that's it.

It doesn't take billions of dollars and all human knowledge to make a single human level intelligence. Just some hormones and timing. So LLMs are mostly a dead end. AGI is going to come from differenst machine learning paradigms.

This is all mostly hype by and for investors right now.
