Is running an app on ethereum still over 100x the cost to run it on, say, AWS? I hear CEOs talk about how this will revolutionize the world, but realistically no one needs a cryptographically secure immutable ledger to validate that someone is the true owner of concert tickets or whatever. I do wonder, if the only real-world application that needs a cryptographically secure immutable ledger, is cryptocurrency.
