Just look at Bitcoin, Ethereum, Counterparty and all the related startups around the cryptocurrency economy..decentralized EBays, currencies, stock exchanges, derivatives will rule the world economy in 6-20 years (not even talking here about the AI & medical revolution).
Politicians, old money and the most sociopathic CEOs will rule the world economy, just like they did last century (these categories are not mutually exclusive). Technology doesn't matter at the top; it's just another mechanism for screwing over adversaries. Some of today's behemoths will fall, but more will come out of the shadows to replace them.
