I'm not doomsaying, I'm saying "let's fly planes in a way that has a better impact on the environment". Innovation is key and reducing fuel burn has a *central* goal in aviation for decades...
Like are you gonna tell me, the current way things are is perfect, we are at the pinnacle of innovation, no where left to go? C'mon man, we'd still be in horse and buggy with that attitude. Let's just find a way to do what we do but cleaner...seems perfectly reasonable to me.
