Kind of unrelated to the article, but does the Moore's law joke about the cat constant make any sense? The `-C` constant should be on both sides of the equation (since the formula is future computation _relative to_ current computation), and thus cancel out. As it stands, the equation doesn't make sense when 'Number of years' is zero, and is inconsistent between calculating twice in 2-year intervals and calculating once with a 4-year interval (as an example).
