we can think of a phenomenon as exhibiting complexity over a given time frame if there are so many interactions that one cannot reasonably forecast the outputs based on the inputs. By this definition, weather would be complex over the time span of a day but not a month. This is why it is relevant not only that things have become more interconnected, but also that processes have become faster. These two variables combined mean that the amount of interactive complexity previously contained in many months of, say, local conversation and letter exchange might now be squeezed into a few hours of
