There was a publication, maybe in german, not sure, which stated that bumblebee can’t fly due to their aerodynamics which i think assumed that a bumblebee was a fixed wing aircraft, which it obviously isn’t. Or maybe it was a hoax to proof that hoaxes spead and can’t be retracted. Not sure. I think it’s quite old actually, dating back to the 1920s or 30s.

Absolutely! Once false information is out there it can’t be retracted even if the article itself is retracted. Bumblebees can’t fly and vaccines cause autism are good examples of that. The only difference i can imagine is that LLMs have a much larger reach and may spread shit faster
