I don't understand why Ethereum developers have to suffer so much upgrading from ETH Proof of work to ETH 2.0. While they can develop a new network more easily, removing the disadvantages of ETH 1.0. Then they create a pool for users to migrate from ETH 1.0 to 2.0 and that's it. Updating and upgrading ETH to 2.0 takes a lot of work and time, while with the same effort they can create a new better net, in fact many new networks were born before ETH could. upgrade like BSC, Polygon... with the experience of the ETH team, I believe they have the ability to develop more expensive than these networks, why don't they have to suffer to upgrade how many times have they broken their promise to the community? ETH 2.0 can move to POS
