I kind of like this metaphor but on the other hand airplanes are one of the hardest parts of the modern world to decarbonise. Maybe we should check in with you in 6 months when there's 42 degrees in Sydney and see how you feel about them.

I'm not sure I see your point. I'm also not convinced you got mine (did you read the thread?)

Understand how incredible this sentence sounds. We made machines which can FLY. We can go to places unreachable before, incredibly fast! This was unthinkable even a few years ago. Even well educated people are mystified by how they work. Again: metallic tubes. Which fly. With us in them! 2/

This is completely magical. And yes, there were reasons to be skeptical, but at this point, it is pretty clear planes can, in fact, go to faraway places in mere hours, where even boats (our best boats!) would have taken months—forget about walking. Planes exist! Is there any point in walking? 3/

There are a few wrinkles of course. These miracles of physics engineering, are quite expensive, and right now only a few select companies can build them or lease them, even wildly subsidized. The tickets ain't exactly cheap, and you may not always get your flight, or seat, even paying for it. 4/
