The original long bet was whether or not computers could pass the turing test by 2029: https://longbets.org/1/ You'd think that LLMs fulfill this, but I do wonder if a clever human could still discern between them given their particularities. https://longbets.org/9/ is another interesting one depending on whether you think…
