Already in the first few lines of the article, there's a reference to a post-1998 date, so I started wondering about the veracity of the (1998). There's no clear reference to the original publication date, buy plenty of references to dates much later - the copyright notice says 2001-2014. But, lo and behold: https://web.archive.org/web/19980206223800/http://norvig.com/21-days.html https://web.archive.org/web/19980206223800/http://norvig.com... It's a very different article, but at the core, it's the very same idea. Pretty fascinating that it apparently has been "ghost-edited" to stay current.
