We should start pricing our satoshis in joules or hashes per sat because fiat currencies are only temporary. What counts in the end is the energy you get for a satoshi. If the game theory around Bitcoin works, this amount will rise forever.
Very cool idea. Purchasing power of sats will rise forever though, and energy efficiency of hashing always changing, so... I think sats just becomes a new SI unit and all fiat must measure themselves in sats. 😁
