We know time because we trust it worldwide.
It is the only language that is globally agreed upon besides some differences in daylight savings time acknowledgements during certain parts of the year. Money is another story. It is a language that the governments made up and the public had to follow.
With Blockchain we can achieve global agreement on the price of any asset that will be steadily realized over time. The more decentralized the more fairly it will be realized. The more decentralized a Blockchain is the more we all have a say, a vote, a voice in the said asset. The more centralized Blockchains may survive but they will not be the dominant players in their respective industries.
We need to keep things more decentralized so that we all can be speaking the same language.
