I remember watching IBM's Watson soundly beat Ken Jennings on Jeapordy. One of the things that sticks out most to me about the memory is that Watson had a confidence rating score for each answer it gave (and there were a few questions for which it had very low confidence). I didn't realize it at the time, but that was actually pretty impressive given the overconfidence issues LLMs have nowadays. Of course, citing sources would always trump any kind of confidence rating in my mind; sources provide provenance, while confidence rating can be fudged just like a bogus answer can.
