Subject: Re: Anybody read BRK-B.com?
A clear sign of text like that being AI generated would be some confidently written mistakes (hallucinations).
I haven't read much of this site, have you noticed any howlers?

I've asked an AI to summarize some research work in other areas (e.g. Nobel prize winning work where there's a ton of papers on the original work and papers that follow up on the original work), and the AI often makes (bad!) mistakes.
I concluded that if it's an area in which I'm a domain expert then I don't need a mistake-prone AI to summarize something for me, and if I'm not a domain expert then I don't trust anything the AI says.
