that is most convenient for the teachers
Nope, also extremely inconvenient to them. It’s only actually convenient for a small selection of neurotypicals with ideal or near ideal home lives/parent involvement, while nearly every other kid benefits from basic adhd accomodations like fidget toys or being allowed to sit/lie wherever to do their work. We haven’t made any significant progress on teaching since the victorian era.
My opinion is that the probability of life developing on another planet, advancing to interstellar travel, and being physically close enough to us to visit us during the last few million years is so implausibly tiny that anyone seriously asking about their relations with human beings can be safely dismissed as a complete rube.
