@munificent This is not a popular viewpoint round here, but I think the sudden concern about externalities is weird. Nobody cared about video cards energy consumption as long as they were used only for gaming.
Societal impact is potentially much more important, but it really depends on what exactly are LLMs capable of. If they can do everything humans can do (which seems hard to believe, but then it's hard to believe they work as well as they do in the first place), then we're all hosed anyhow.
