EVERY SINGLE use tall people have ever had, has disappeared by now.
Need to reach something that's on a high shelf? Yeah, you could ask a tall person to get that for you, BUT you could also just get a step-ladder.
Need someone to look above a tall obstacles? Heh, ever heard of Google maps?
And this is ONLY the case with tall people. There are no gizmos or gadgets that can make a tall guy fit through a narrow tunnel or something like that.
Every single advancement humanity has ever made has made tall people a little more useless...
