We live in a representative government where the people elect representatives who make decisions. In the future, the overwhelming complication of voting on decisions (rather than decision-makers) can be overcome.
Democratic decision making will take place on a very wide range of decisions, in real time, and among effected participants. All available evidence, argument, and education that is relevant for each vote will be publicly and conveniently accessible. Some votes will be continuous, while others will have deadlines. Bureaucracy will be vastly eliminated. Laws and tax rates will quickly adjust to optimal. Justice will be swift and accurate. Power will be decentralized.
