Forget what some people are calling Web3.0.
The first phase of the internet involved taking real world information, and moving it into a digital, connected format – i.e. making web pages.
The second phase of the internet involved taking that newly minted digital stuff, and bringing humanity into the picture (i.e. web pages that are “social”).
The third phase of the internet will involve taking “stuff” that was originally digital, and making it “live” in the real world. All that mobile phone geo-location stuff is just a tiny (and honestly, not very interesting) part of that.
The fourth phase of the internet is already upon us as well, and interestingly enough its as much about hardware as software. This phase involves breaking the physical constraints of the internet and allowing it to work seamlessly through ad-hoc, peer-to-peer, wireless networks (i.e. there’s no ISP and no phone company involved, except maybe for the long lines). This also involves replacing TCP/IP with DTN – especially if humanity is going to do anything useful in the rest of the solar system.
