It is quite pathetic that a purported 'future of payments' is so inefficient in so many ways. This is why I will never participate in systems like bitcoin that consume hundreds of TwH (and growing) each year.
Its not a payment system (unless the transaction is sufficiently large). It's more like digital gold. But gold has a track record of holding value over millennia. Bitcoin is only a decade old. Will it hold up over time? Nobody actually knows.
Edit: I guess the summary would be that cash & gold are decoupled from electricity (even if it takes some to create/mine them), but Bitcoin's entire existence depends on continuous availability of (cheap enough) electricity.
