Mid and upper models of Flair Espresso maker are plastic free in the brewing areas and around $400-500. Tradeoff is it’s manual but that is just more proof of work. Pair with a metal hot water kettle and you’re all set.

    Quantum resistance was discussed during taproot development. This is eternal September. Using address formats and cryptography available, changing it would only help potentially defend against a long range attack and NOT a short range attack. Not taking a side either way, just important to set the record straight on the conversation and thought process at the time, right or wrong. If you disagree that’s fine. But to say it wasn’t considered is factually inaccurate and can be verified from posts and emails during Taproot.
