This post is part of the Rerunning the Sequences series, where we'll be going through Eliezer Yudkowsky's old posts in order so that people who are interested can (re-)read and discuss them.

"We learn to walk and speak in childhood, and nobody regards these as childish activities." - George Walford, Beyond Politics 1990
