> Have you ever done the experiments to prove the Earth is round?

I have, actually! Thanks, astronomy class!

I've even estimated the earth's diameter, and I was only like 30% off (iirc). Pretty good for the simplistic method and rough measurements we used.

Sometimes authorities are actually authoritative, though, particularly for technical, factual material. If I'm reading a published release date for a video game, directly from the publisher -- what is there to contest? Meanwhile, ask an LLM and you may have... mixed results, even if the date is within its knowledge cutoff.
