I'm curious about this, I try to stay up on what's going on in the crypto world and it's my understanding that the vast majority of crypto blockchains are still using proof-of-work, which is what I imagine "planet destroying" is in reference to. Per wikipedia https://en.wikipedia.org/wiki/Proof_of_stake https://en.wikipedia.org/wiki/Proof_of_stake The biggest proof-of-stake blockchains by market capitalization in 2021 were Cardano, Avalanche, Polkadot and Solana. Other prominent PoS platforms include Tron, EOS, Algorand, and Tezos. There have been repeated proposals for Ethereum to switch from a PoW to PoS mechanism. In April 2021, the Ethereum Foundation announced that it planned to switch to a PoS system by the end of 2021. This has since been pushed back to the second quarter of 2022. --- So if most of crypto transactions are conducted on proof-of-work chains, which do require burning large amounts of electricity, why would this make you think someone doesn't know about the current state of crypto. What exactly about the current state of crypto is incompatible with this critique?

>>What exactly about the current state of crypto is incompatible with this critique? Ethereum is by far the most widely used cryptocurrency network, and while it consumes a lot of energy relative to the number of transactions in processes, and a lot of energy in absolute terms, it consumes on the order of a thousandths (0.1%) of the world's energy output. It will have switched to Proof of Stake long before it grows large enough for it to account for a materially significant portion of global energy consumption. So the rhetoric used above, which makes the generalization that "Crypto is a planet-destroying ponzi-scheme", is entirely hyperbolic with respect to the environmental criticism (and a blatant mischaracterization with respect to the ponzi-scheme allegation).

  Ethereum is now estimated to consume energy equivalent to or greater than mid-sized countries like Greece[1]. You can paint it as tiny, but 0.1% of world energy output is still enormous, for providing what is for the most part a highly speculative set of financial instruments to a limited audience. It's been "about to go PoS" for several years now. The fact is it hasn't. When it does, you can tell people their concerns are out of date. About Ethereum. Bitcoin isn't even going there and its consumption is as bad or worse.

    I don't disagree with most of your comment, but I do want to point out that the code to power Ethereum's switch to PoS is actually built out now and is in its final stages of testing. The latest Kiln test network is effectively a release candidate. At no point in the past several years has that been true, so it's comparing apples to oranges to say it's been "about to go" for that long.

      I will welcome it when it does, don't get me wrong. That honestly removes a major issue I have with cryptocurrency (at least with Ether, anyway). There are a host of more theoretical reasons I'm not buying into the ecosystem, but remove that negative externality and hey - you do you, not my bag but you aren't hurting others. I'm sure it is closer than ever, if it wasn't then there's something wrong with the development process! I sincerely wish the various people involved good luck in this venture and a speedy success in moving it to production. In the mean time I'm still going to get pissed off at people saying that energy concerns are outdated, especially when they're referring to the whole cryptocurrency ecosystem.

        Don't forget that traditional banks consume lots of energy as well. Their armies of employees and tellers are required to drive an hour or so every day, they maintain tons of physical buildings, truck around piles of physical currency etc. Traditional fiat is given legitimacy based on government's monopoly on violence inside their borders which often result in wars. Nothing is free and I'm fairly certain that crypto will end in less energy consumption, not more.

One day, could, will. But still isn't and doesn't. With a background of a world scrambling for cleaner power to mitigate climate change. That's the problem.
