I had the incredible pleasure of spending a cocktail party seated next to Stewart Brand back around '94. I did not know who he was, but by the end of the evening I was convinced this was the most witty, empathetic genius I'd ever encountered. And I've met quite a few. At one point, astonished at his quick wit, a group of us throw topics at him, and he knew them all, and the biting sarcastic jokes about them was how he let us know. Extremely fun guy.
