There are indeed. You know "The Last Man" by Mary Shelly (wife of Percy) is one of my favourite books of all time.

I hope they can deliver, but I'm not entirely sure that what they are going to deliver is really that different from other blockchains claiming to be the web 3.0. The more buzz words and hype I hears about these things, the more I think they will be willed into being top of the market cap by people that desperately want them to be there, but ultimately after mainnet launches, we will certainly see.
