Banks will use progressively less energy per capita as bulk data processing becomes more energy efficient, assuming they donʼt transition to using proof-of-work.
Ultimately, mining should be banned from the surface of Earth. Let miners build orbital solar panel infrastructure close to the Sun where power is plentiful. See Bitcoin developer Peter Todd's 2017-09-10 presentation on the subject (transcript).
In my opinion, it was when anti-trust laws did not trigger upon Google acquiring YouTube because Google Video couldn't compete. That meant it was open season on start-ups that otherwise might have grown to kill Google or other big tech companies like Apple, Facebook and Microsoft.
Amazon Prime is meant to invoke the sunk cost fallacy in your mind. Why shop around when you've already sunk over 100 USD per year into “free” shipping? This mental bias towards shopping with Amazon is the cost and is part of an overall anti-competitive strategy. See “The making of Amazon Prime, the internet’s most successful and devastating membership program”. Jeff Bezos has been explicitly anti-competitive on this point:
“I want to draw a moat around our best customers.”
You don't leave a moated walled garden unless the Lord who maintains the moat permits you. And even then, they'll strip you of your DRM'd digital goods (TV shows, movies, audiobooks, ebooks) as soon as you cross the drawbridge. The strongest supporters of Amazon are the ones who have thousands of USD of such digital goods locked up with them since they can't leave without being stripped of things they bought.
As for video streaming, it's going to take a breakup of the Big Tech monopolies via revival of anti-trust laws to fix that. Hear the first chapter of The Internet Con (skip to 2m5s) by Cory Doctorow for more on that.
Keyboards were so nice when you wanted to accurately input characters without putting your faith in auto-correct. God help you if you need to input something not in its dictionary like someone's name.
