What are the heuristics for computing your chart? How much energy was it to make the plastic on the credit card terminals? Do bankers drive Priuses or Cadillacs? What if Bitcoin eliminates 50,000 bankers's air-conditioned office desks?

Is Bitcoin's cost per transaction a fixed number or improving in efficiency? What if planes were "downvoted" 10 years after invention due to inefficiency over rail transport?

Which side of history will you be on?
