I welcome the reduction in energy consumption, but do not understand how a Proof of Stake approach does not effectively make Etheureum extremly uninteresting for non-whales.
Yes, but I think the “whales” comment was a reference to the large upfront cost of staking in ETH2. At the moment a single validator requires depositing USD equivalent of $94,399.36 (32 ETH).
Staking pools can be decentralized or centralized. For Eth2 to have a bright decentralized future, it's important that decentralized staking pools can emerge and thrive.
