My friend is a leading research chemist and he, and one other person in china, are working on this one particular field - individually - so there would be little information out there. I asked ChatGPT 4o to give an overview of what he was doing based on the little information I knew. He was astounded. It got it spot on. I asked it to elaborate and to come up with some new direction for research and the ideas it spat out were those he had considered and more.
