At the moment Ethereum "2.0" is a scheme to manipulate the market price of ethereum by printing a whole bunch of additional ethereum out of thin air and awarding it to people who lock up their funds completely out of circulation for an unspecified time (considering that this "launch" is now years after the the original claims, the claimed >1 year should not be read as strong evidence of only one year).
Because the new system is completely unusable there was absolutely no legitimate purpose to start this lockup at this time as a public system rather than just some fake-money test network.
Once (if?) it becomes usable it will have the additional ultimate property of further enriching the beneficiaries of Ethereum's 72 million coin pre-mine, since those super large positions are effectively illiquid (can't sell more than a small share without crashing the price), its low risk for those parties to place large amounts in lockup.
The concept of "proof of stake" has fundamental soundness problems which have not been addressed except by obscuring it with deceptive obfuscation and protecting it against peer review through sheer complexity. https://download.wpsoftware.net/bitcoin/pos.pdf
Adopted in a very successful manner? What does that mean? What a ridiculous standard. Technology exists, if you don't use it its not the fault of the tech.
Its not hard to understand: "if X has green and non-green options, and you choose non-green, that doesn't mean you can claim X is non-green."
The issue was an implementation bug afaict and from official responses.
Solana is clearly BFT, unlike what Emin claims.
To be fair, I don't expect Solana to be as centralised as other chains only for the reason that you need a gaming rig to run a consensus node. Solana is not centralised for the reasons you mention.
A central blockchain has not a lot more energy use than a regular database. It's the distributed trustless proof of work kinda blockchain that mindlessly burns up energy.
A central blockchain is an oxymoron: a pointless waste of time. A distributed, trustless, permissionless data structure on the other hand is a useful thing to have for a small number of use-cases.
