Every time you connect to the internet, you pass through time, space, and law. Information is sent out from your computer all over the world, and sent back from there. This information is stored and tracked in multiple locations, and used to make decisions about you, and determine your rights. These decisions are made by people, companies, countries and machines, in many countries and legal jurisdictions. Citizen Ex shows you where those places are.
Your Algorithmic Citizenship is how you appear to the internet, as a collection of data extending across many nations, with a different citizenship and different rights in every place. One day perhaps we will all live like we do on the internet. Until then, there's Citizen Ex.
