Very weird submission, the linked post is 2 years old. Received no attention whatsoever, then the Copyright is updated to CC0 4 hours ago and suddenly gets posted to Hackernews.

Furthermore, the proposal is a bit non-sensical. It's still possible to fork Ethereum, as a staker you must choose which chain you want to stake. You cannot stake in both because you would get slashed. But if you decide that Ethereum-fork is your preferred version of Ethereum you can turn-off your Ethereum validators and only validate on Ethereum-fork. That's OK.

The market will decide which network is most valuable.

How is it determined on chain if you’re validating on a fork?
