At a recent conference, Vitalik Buterin believes that ETH 2.0 encapsulates the same vision as ETH 1.0, but is an update attempt to achieve the same vision. In addition, Ethereum co-founder Joe Lubin said that ETH 1.0 is just a prototype and needs to introduce something that we know can't be extended. Bitcoin core developer Jimmy Song commented that the smart contract to equity proof, then ICO, and now the currency will eventually change in the future. This is what central players can do, and they publish stories that everyone believes because they are central. Song believes that they are changing the narrative style to attract more people to invest in ETH.
