Sounds like one use-case of for same-sex couples to have biological children together. Which is pretty neat IMHO!
Not to say that the more macabre use cases don't exist, of course.

As usual, it sounds like the technology could be used for genuinely good things.
It could be used for horrible things too, yes, but that's often how it goes.
You know you fucked up real good when Mr. Oatmeal gets involved.
No, that's not really a useful way of modeling it for the case of light traveling through a linear medium.
The absorption/re-emission model implicitly localizes the photons, which is problematic
think about it in an uncertainty principle (or diffraction limit) picture: it implies that the momentum is highly uncertain, which means that the light would get absorbed but re-emitted in every direction, which doesn't happen. So instead you can make arguments about it being a delocalized photon and being absorbed and re-emitted coherently across the material, but this isn't really the same thing as the "ping pong balls stopping and starting again" model.
Another problem is to ask why the light doesn't change color in a (linear) medium
because if it's getting absorbed and re-emitted, and is not hitting a nice absorption line, why wouldn't it change energy by exchanging with the environment/other degrees of freedom? (The answer is it does do this
it's called Raman scattering, but that is generally a very weak effect.)
The absorption/emission picture does work for things like fluorescence. But Maxwell's equations, the Schrödinger equation, QED
these are wave equations.
I kinda assumed any Mars mission would include some simple centrifugal pod. Seems like even if it's just for sleeping it would be useful.
Dispersion and nonlinearities would like to have a word ;)

IIRC chvt is a privileged command, which makes sense (if an unprivileged user could execute this command they could effectively brick the computer for a local user).
That said, my understanding is that modern DE's are given a lot of access, so presumably chvt is allowed (and in this case, is required because as others mentioned, password is required). So the only other option is to fail unlocked, which is all kinds of Bad.
And over twice the GDP.

That's...pretty believable.
Although you can use case insensitive filesystems with Linux, and case sensitive filesystems with macOS. I believe the case sensitivity is a function of the specific filesystem
but yeah, practically, the root for Linux is always case sensitive, and APFS ~~ain't~~ is only if you ask it to be ( https://support.apple.com/lv-lv/guide/disk-utility/dsku19ed921c/mac ).
