• I've been checking the source of quotes for my forthcoming book, and the performance of Gemini is extraordinary. I paste the quote into Google, and Gemini will barge in with the wrong answer over and over again. It's not an occasional thing - it's reliably wrong. Very odd.
  Quoting@TimHarfordTwice in past week I've pasted quote into Google to check the source, and Gemini has barged in with the wrong answer. CS Lewis quote from The Seeing Eye (1967) was placed in The Screwtape Letters (1942). Alfred Loftus quote (1857) attributed to Austen Layard (1849). Gemini 0/2.

• x.comMathematicians are unhappy about OpenAI. The gist of their argument is that they form a community that trains young people. When AI started producing breakthroughs on hard mathematical problems, I asked what a very smart 17-year-old would feel. Do you still choose a math major and train yourself to prove difficult results by hand? This crisis has been coming for a long time. When I was a kid, the four-colour theorem was proved by a computer, in 1976. An intense debate followed. Does it count as a proof? I wrote my PhD thesis using symbolic algebra software. To my knowledge, nobody then would…

• Wow, this tweet went very viral! I wanted share a possibly slightly improved version of the tweet in an "idea file". The idea of the idea file is that in this era of LLM agents, there is less of a point/need of sharing the specific code/app, you just share the idea, then the other person's agent customizes & builds it for your specific needs. So here's the idea in a gist format: https://t.co/NlAfEJjtJV You can give this to your agent and it can build you your own LLM wiki and guide you on how to use it etc. It's intentionally kept a little bit abstract/vague because there are so many directio…
