I get the impression that every influential entity has plans of creating its own currency. There's even speculation of Facebook creating its own ICO.
Do you think that fractionalized ownership will be applied to everything? Are all assets going to be tradable?
It is a good idea but I think it will appear in a very distant future. Our world is still growing everyday but it is not so modern. What you say will definitely happen in the next 100 or 200 years. All countries will merge into one and technology will always be utilized.
It is true that the future in which the blockchain is going to become dominant is not going to happen soon and it will take considerable time but I do not agree with the vision that all countries will unite and form a single one, there are cultural differences that should be preserved, a world where everyone is the same and it is uniform is not only very boring but maybe even dangerous for the progress of humanity as a species.
