Does anyone read bottom to top? I don't think I've ever heard of a language like that.
Im not trying to come across as snarky I'm genuinely asking because that seems to be the main problem with this one.
EDIT: From what I can find there are in fact a few languages written bottom up but they are not common at all and it looks like there are less than 100000 current speakers even if you added them all together.
We could do space mining today if their was any incentive to do it. There just isn't any reason to currently but if we start using fusion power (which China has made strides in recently) it would make a ton of sense to get He-3 on the moon.
Hell I give it 20 years before a private company at the very least tries to move one of the really rare earth element rich asteoids into an orbit around earth. From the calculations I've seen we could technically do it with current rocket tech assuming proper planet alignment.
