There was some confusion. I originally read Wiseowise's comment as a failure to think of anything that could be "useful but bad for humanity". But given the followup response above I assume they're actually saying that LLMs are similar to tools like the Internet or Wikipedia and therefore should simply not be in the bad for humanity category.

Whether that's true or not, it is a different claim which doesn't fit the way I responded. It does fit the way Libidinalecon responded.
