so this has been an issue that keeps coming up for a while, but i don't really understand the issue.
* As others have asked, how much is bitcoin supposed to use? What's the right amount and why? How is that number better/worse than the amount of resources spent on existing financial infrastructure?
* We are rapidly progressing towards an era of free (extremely cheap) clean power. Just today (https://electrek.co/2017/11/08/chilean-solar-down-26-as-impo...) incredibly low bids for solar projects were submitted in Chile at 2.15c/kWh. That's insanely cheap. We're not there yet in having ubiquitous cheap clean power obviously, but neither is bitcoin "there" in being able to replace much of traditional financial infrastructure. But the point still stands: will bitcoin's energy usage still matter in the not-too-distant future?
