[delusional]

> there's years if not decades of R&D work into how to best use the ones we have - how to harness the big ones, where to embed the small ones, and of course, more fundamental exploration of the latent spaces and how they formed, to inform information sciences, cognitive sciences, and perhaps even philosophy.

I think my sense of "dead end" would entail none of those directions panning out into anything interesting. You would "explore the latent spaces" only to find nothing of value. Embedding the LLM models wouldn't end up doing anything useful for whatever reason, and philosophy would continue on without any change.
