What coping drivel; the majority of humans will decidedly NOT be going on spacefaring travels to the outer edges of the universe, and they're not going to specifically exclude all average height and taller people just for convenience...
They'll just make seating areas and overall living spaces larger, as they're not missing out on a 6'2 140 IQ scientist/astronaut because of "comfortableness"; does this bluepilled retard even know how evolution works?
Tall Chads will continue to reproduce at a higher level than manlets, and continue to gradually increase average worldwide height; I really doubt spacefaring will advance that level without humanity either being destroyed or realizing sci-fi type warp drives are scientifically impossible.
