With this statement, "All world currencies will become cryptocurrencies, and the value will flow as freely as the information today." You can argue. I think that fiat will never become cryptocurrency. Yes, and ETC20 is already outdated technology. Now they use ERC223 and ERC721.
It's alright if they aren't themselves. Most major Fiat currencies like USD and Yen are already usable as a cryptocurrency and even governments and central banks are working on creating their own cryptocurrencies. There is indeed a difference, but you can argue there isn't ;-)
We strongly believe most assets and currencies will be tokenized in the not so far future and therefore exchangeable on Liquidswap.
