It's a bit of a strange comment. One could certainly argue that in a proof of stake system a dynamic naturally exists where those who stake more earn more, and can stake more to earn more to stake more... The thing is though is you could say the same for traditional crypto mining. In either situation one person holding too many opportunities to author new blocks is a chance to double spend (though highly mitigated by simply waiting longer for newer blocks to come through before accepting trades).

Would you say that the existing PoS systems (like Ethereum 2) aren't as centralized as he mentions, then?

  ETH2 doesn't 'exist'. There is a heartbeat chain right now, but it doesn't actually do anything. Getting to the next step(s) is the hard part. Full PoS decentralization does not exist yet. Many attempts exist. Some better than others. Sadly, the complexity (rube goldberg) of PoS far outweighs the simplicity of PoW.

That sounds a bit no-true-Scotsmany. > Sadly, the complexity (rube goldberg) of PoS far outweighs the simplicity of PoW. Yes, and the huge energy usage of PoW far outweighs the zero energy usage of PoS. That's the tradeoff.

      It doesn't exist because ETH2 doesn't exist. It is the one blockchain that I see as being focused on full decentralization, instead of just stopping at variations of tendermint and a bunch of "approved" validators. Contrary to popular belief, PoS isn't zero energy usage. My very very very large ETH1 gpu mining operation sits next door to the same large data centers powering all the cloud providers. All getting power from the same hydrodams that would just go to waste otherwise. It isn't like the power can be easily used in other ways... transmission of power is expensive and intrusive. Bitcoin is an issue because of supply/demand... when the reward goes away, so will the miners. Difficulty will drop to more acceptable levels to cover the loss. ETH1/ethash at least tries to peg to a specific type of hardware that actually has a better roi with older models and doesn't need the latest / greatest. The tricky bit to make ETH2 work will be the use of zkSnarks. What nobody talks about is how compute (energy) heavy they are currently. It is a bit of moving the goal post if we're going to just end up building asic's again.

Everyone grows at the same rate though. If someone stakes 1% of the total pool and someone stakes 99%, then after making more they will still be at a 1:99 ratio.
