I had an unexpected experience with a live LLM chatbot when I was trying to cancel a hotel booking by phone. This seems like a place where an LLM might be more useful or quicker than a standard decision tree. Anyway after talking to it, and it appearing to understand, I got kicked to a decision tree

I'm sorry, what? In writing my first monograph, I spent six weeks trying to track down a citation in TWO languages I didn't know. And good thing too, because the citation was wrong. That's scholarship. That's research. You know, the thing we're trained to do?!?
The reactions of some researchers on Twitter finally being held responsible for not having read the very paper they submitted are... something. Mainly, they don't think they should have to check every citation or make sure the data is real and accurate. Because it's too hard, I guess.

I had a Yeltsin-esque reaction in a Michigan grocery store after seeing hard to find and expensive bottles of liquor being cheap and readily available in the US. I don’t think it is possible to buy any mezcal in Aus for less than $100aud, but a nice bottle of it was $40USD here. End sin taxes!

I see no reason for TACs to not randomly select 5-10% of the time from the submissions (or the top half of submissions). The only reason would be the tacit agreement that ranking proposals is somewhat arbitrary

I find it funny that when reading books on SETI, many authors describe the inherent chauvinism in assuming intelligence as an “evolutionary goal”, but to describe the pinnacle of technology they all invariably put the peak at radio telescopes. Perhaps radio astronomers are also chauvinists lol
