Wow, He used my wife's portrait of himself. I was there the day she took it, it was the opportunity of a lifetime to meet one of my heroes, and he didn't disappoint. Knuth is incredibly sharp, lightning sharp for his age. He plays Emacs as masterfully as he plays his pipe organ in his home. I watched as he whipped around different buffers of literate programming, as he demoed some new angle on the properties of Sudoku solving algorithms. I asked him if he had been keeping up with machine learning, and he instantly name-dropped a dozen papers/authors he had read recently. I have to say, I'm worried. Just in 2020, we lost of a lot of greats, including Jon Conway, Larry Tessler, Chuck Peddle, Bert Sutherland, Frances Allen, most recently Brad Cox. We're losing not just a lot of history, but a lot of the historians themselves, the people to whom can tell the stories that may not have been written down yet.
