For anyone interested in maps I would highly recommend this a16z podcast: link
Maps are diagrammatic representations of our world around us. Unknown areas are blank spaces, known areas are full of available detail.
As a species, we humans are becoming predominantly sensor carrying data creators. Not just our watches and our phones attached to our bodies, but our cars and our homes are causing tidal waves of information to flow and to be captured.
One of the consequences is a mapping of life as we know it. You are most likely creating a map of your life online and in ever more detail.
You also have a say in what it says about you.
