OK the statement is wrong as given. But why do so many people say it? If the quoted phrase pops up 400K times in Google, you'd think that somebody said something somewhere that somehow established the phrase in people's minds. Perhaps I should check Internet rumor sites. Maybe it came from a chain letter. Thinking about it, the adjective nontrivial may have been in the statement. But who knows what that means?

When I Google "all software has bugs," I get over 400,000 pages. Also I've heard somewhere that this has been proven. If it has, by who, and where can I find a copy of the proof?
