I think the OP's comment is entirely fair. Karpathy and others come across to me as people putting a hose into itself: they work with LLMs to produce output that is related to LLMs.

I might reframe the comment as: are you actually using LLMs for sustained, difficult work in a domain that has nothing to do with LLMs?

It feels like a lot of LLM-oriented work is fake. It is compounding "stuff," both inputs and outputs, and so the increased amount of stuff makes it feel like we're living in a higher plane of information abundance, but in reality we're increasing entropy.

Tech has always had an information bias, and LLMs are the perfect vehicle to create a lot of superfluous information.
