Web 3.0 is certainly an improvement over the previous versions. Arguably even an improvement over "real life".
I think of the various cryptocurrency layers as the equivalent of different fiat currencies, eg USD, EUR, GBP etc. What you can buy with one is not necessarily the same as what you can buy with another.
The improvement of web 3.0 is that we can cut out the traditional financial system. That is, I can exchange LTC for POLYCUB independent of a middleman. That is virtually impossible for fiat currencies unless you go to black markets!
Additionally, web 3.0 supports the development of decentralized, independent communities which can use the cryptocurrency layer to crate their own ecosystem as simple or all-encompassing as they want.
Go HIVE!
