He wasn't ignoring anything, he was pointing out that that criticism is based on outdated information. Almost all modern blockchain designs (from the past ~10 years) do not promote energy waste via PoW.

It's fine to point out the energy waste of more traditional PoW chains (particularly Bitcoin, which accounts for the bulk of PoW), but to frame that as a problem with blockchains in general is misguided.

    Bitcoin is still the biggest player in the cryptocurrency world, so still a lot of wasted energy.
