Yup, you never get to \omega that way. Cardinality is a coarser notion than "ordinality". So your example shows that Card(\omega * \omega) = Card(\omega) = \aleph_0, even though \omega * \omega and \omega have different order ty

Thomas Pynchon's essay does a good job, I think, of explaining what the Luddites really fought against, and he does not, as this article seems to suggest, say a Luddite is "someone who opposes technological progress". https:
