Counting

We have never been more able to actually count things in the history of the world. No need to guess, estimate, or interpolate when you can actually count it all out. But we don't do it, or we don't do it as much as we could. 

Where we can count, we should. Where we can ask, we should. I do not go a day without noting somebody assuming where they could measure, estimating where they could count. It is no longer functional behavior but the less and less functional legacy of the pre-information age. The faster we are rid of the habits of guesswork, the better.
