People were talking about fancy new technologies and called it Web 3.0, 4.0, ..., 53657.0, (I do not remember all the version numbers, though). Am I too gullible?
Now there are those fancy new ICOs that claim to use blockchain 3.0, 4.0, ... technologies. What do you think about them? Is there a slight chance that Ethereum (which is considered blockchain 2.0) can survive against those fancy blockchain X.0 ICOs, where X > 3?
