Lyn is one of the smartest people out there. She raises some legitimate concerns here for sure. However, to play the devils advocate I feel there’s only room for one major PoW based blockchain. Ethereum as a pure dApp and smart contract platform might just be able to pull off being PoS. No, it won’t be anywhere close to as decentralized or secure as Bitcoin but maybe it just doesn’t need to be. Idk. I’m generally skeptical of PoS and the need for stuff like Solana and Cardano to even be a blockchain at all, but the Ethereum developer eco system is really mature and I can hesitantly agree that some of its utility holds potential. It just won’t ever compete with Bitcoin.
