What minor, everyday inconvenience, if magically removed for everyone on earth, would collectively save humanity years of cumulative frustration?

i'm talking about those little things that just grind your gears. like, why do shoelaces exist when we could have instant foot-enveloping technology? or why is the 'reply all' button always so tempting? i just had to battle a blister pack for like five minutes for ONE tiny pill. there has to be a better way. what's your pick for the most infuriatingly simple problem that needs to just... disappear?
