1) As silly as it is to type this out, the biggest problem with digital direct democracy would be that old people don’t trust the internet. We want everyone to have a say in society, but they won’t know how to use this technology and will use their current control over society to suppress this system. Even worse, the people with a lot of power may try more violent tactics to suppress this system if it grows too powerful. This is the point where we must hope the police and military stand down. It’s not like anyone can suppress a truly good idea anyway.
2) The second biggest problem is probably people not quite understanding how the system works. Everyone fears what they don’t understand. Hopefully the FAQ will answer any questions people have. If there are any others, please leave them in the comments. The most important concept to remember is that D-2.0 is a tool to decentralize decision-making power to entire communities, not a new government in and of itself.
3) As for people gaming the system, that’s always going to happen. Fortunately D-2.0 counteracts this by firmly giving control of each piece of legislation to its creator while still allowing others to edit and comment on edits. Then it firmly gives control over whether or not to pass the legislation to everyone who cares enough about the issue at hand to vote. There are no middlemen, no wealthy lobbyists. Just people and their ideas. I think it will be pretty difficult to game a transparent system where emotion can be completely removed from the conversation.
4) It’s sad, but another possibility is that no one steps up to the plate. No one fixes society’s problems and entropy transforms our place into a wasteland. I doubt this will happen, especially if you can do it in the comfort of your own home, but it’s still a possibility. Then I guess we really deserve whatever fate we are given by stronger people, or whatever the puppet leader decides to do. It’s important to remember that D-2.0 is flexible. It can be used by anyone alive who claims to be a citizen of a given place, including current leaders. In fact, it could help them do their job more efficiently. Or it can be used by small, tight-knit communities. When it is demonstrated to work in small communities, D-2.0 can be used with larger and larger states until the world is unified, and divided, in the manner most people so chooses.
