Biggest danger of LLMs as they currently fit into society: the radical consolidation of information flow through corporate-controlled bottlenecks that make current generation algorithmic social media (rancid as it is) look like child's play. When people no longer "search" for things, but simply "ask ChatGPT", the lever of social control is nearly absolute.

(Of course, all this is up in the air. If LLMs become commodities, the situation becomes very complex; the information flow doesn't get quite so consolidated, but it still becomes impossible to tractably analyze, as all the LLMs train off each other)
