title: Décentralisation et taille critique

> Finally, I’d like to end with a few more words about why I think this type of work is interesting and important. There’s a certain grand, global scale of project, let’s pick GitHub and Wikipedia as exemplars, where the only way to have the project be able to exist at global scale after it becomes popular is to raise tens of millions of dollars a year, as GitHub and Wikipedia have, to spend running it, hoarding disks and bandwidth in big data centers. That limits the kind of projects we can create and imagine at that scale to those that we can make a business plan for raising tens of millions of dollars a year to run. I hope that having decentralized and peer to peer algorithms allows us to think about creating ambitious software that doesn’t require that level of investment, and just instead requires its users to cooperate and share with each other.
