It's a very very complex subject. These two gentlemen, representing the left and right of the washing machine spectrum have barely scratched the surface.
Ever wondered why there was no mention of washing machines in Plato's Forms? or Aristotle's works?

If you can find the answers, you sir, will be up there with the true greats.
