Decentralized is the ultimate tech fantasy. It never happens at mass consumer scale. There isn't a single example of that in the last 25 years of the Internet. The reason it never happens, is because most people with a heavy tech-tilt don't understand normal users at all. They fail to understand that they're an extreme minority in terms of product behavior.

You can dig back a decade or whatever on HN, it's a non-stop talking fest about decentralized, everytime anything negative happens, whether this or Facebook or whatever. And yet, ten years later, nothing. Everything mass consumer tech is centralized.
