Um...why would we need some kind of leader in the first place..? Really if you think about it the necesity for a leader or a government comes when people cannot produce on their own food, shelter, clothing etc and so a group of people must lay down rules, laws to leave them dependent forever on coorporations, market and so on for profit reasons. I am pretty sure soon in the future we will have so advanced tech in our homes where we will construct matter from atoms to anything we need.
Anyway here's some interesting links that may take us into new societies like featured in Star Trek.

One truism Government constantly tries to sell is certain "-isms" produce better results in terms of inventing new technology, when in fact, access to information is about the only thing that is needed. Humans are naturally inquisitive, this isn't something brought about by the desire for money. Humans are born with a natural inclination to find out who they are. Racism, religion, celebrity worship, the desire for monetary compensation, that's all taught. So really I do think it's only a matter of time before technology outstrips the need Governance, or even an economy. Because once we see we're all human, and aren't being monopolized by the interests of the most dogmatic of our society, they won't be able to trick us into playing their games anymore, and we'll still be inventing things to change our society for the better.
