 Two final questions. My first one is about what I call the Larry Summers production function So you were successful at quite a young age But what I find striking after reviewing a lot of what you've done and a lot of talks you've given is I find at your current age 62 That when you answer questions on YouTube in general your answers are in some way better or richer than they would have been 5-10 years ago, and they were already Obviously quite good to have gotten you to where you are so for people who are already famous and To some extent well off At the age margin of whatever to 62 for their answers still to be getting better. This is what I find striking You don't have to be modest here, but what is there in the Larry Summers production function that explains this? Well part of the answer I think is He goes back to the first question that you asked I've always tried to surround myself and be around extraordinarily able young people and They probably do learn some things from me But I learn a lot from them both from things they say and know that I don't and From the questions they ask Which? Keep me on My toes. I think that's one answer. I think another answer. And by the way, I flattered that you think it's true I don't know if it's true. I don't know if it's true or not one thing I've always tried to define myself by and Sometimes it's been more successful than other times is opposition to complacency and Not being satisfied with any institution With myself or with anybody and always thinking things can be better and That's sort of the attitude I have To Myself as well. So, you know, I'll be on a plane. I'll be on a plane back tonight and I'll be thinking about the various questions you asked and Which questions I could have given better answers to and then I'll think about those answers and The next time I'm somewhere. I'll give better answers or be better at discussing things Because I wasn't complacent or satisfied. So those would probably be the answers I'd give
