@davidgerard People who really should know better: "Yes! Let's use these things in professional astronomy and astrophysics!"
The banal reality: Among many other topics LLMs fail dismally at, they don't know one of the most challenging practical problems of modern astronomy: how telescopes work. They also fail incredibly complex astronomical tasks tasks like "Can I see this object from such-and-such location?" on the regular. https://c.im/@dpnash/116439620966675196
