It said “cheaper” not “energy efficient”.

Wings are easy, jet engines are hard.

Besides, if you can do it with an electrical locomotive on the ground, the energy conversion to electricity of a power plant should be better than the energy conversion of a jet engine from fuel to movement.

So imo, cheaper seems plausible, energy efficient is a maybe.

If this is not a meme…

You know how you have to look up… errors when you don’t know what they mean?

That.

Figuring out how to do something specific, like UI, works just like that. All the time. It’s “looking up how it works”, then “messing around with it until it does” all the way down.

If you are just starting out, coding something in HTML and javascript might be intuitive, because you can see and run it right away. Otherwise you will have to figure out how to use some kind of UI framework in the language you’re using. Because they’re all different. Yeeeaaah…

I think it’s harder for compiled languages and easier for interpreted ones.
