Shane Legg’s 2028 median

A probability distribution is more informative than one confident date. It also makes the comparison harder: definitions, conditions and updates matter. The 2011 Q&A’s 2028 median should not be confused with a separate statement about a mean or a modal year.

This entry keeps the verified versions and removes the claim that the forecast has remained unchanged forever. Future revisions can be added in the version-history field without rewriting the original record.
