I wonder if that's why people seem to have gotten less intelligent over the past few years (IQ scores seem to confirm this). I thought it was because of social media but maybe high CO2 is to blame. I would never have thought that the movie Idiocracy would become reality; it seemed so ridiculously far-fetched at the time... Even with its 500 year timeframe... Now it looks like it may actually happen for real in only a few hundred years. I wonder if I watched that movie again today if it would come across more as a drama than a comedy.
