So someone is going to load 2.5x as many images because it can be decoded 2.5x faster? The paradox isn't a law of physics, it's an interesting observation about markets. (If this was a joke it was too subtle for me)

Might as well just shoot yourself if that's how you look at improvements. The only way to do something good it to stop existing. (this is a general statement, not aimed at you or anyone in particular)
