We do do this. Have you never been involved in a work conversation where someone says, "Get to the point, you're wasting everyone's time."
Have you never gone to someone to make a request, and you're starting out with a long spiel about your reasons, and the other person says, "Look, I'm busy, just tell me what it is you want."
I see these kinds of conversations a lot. It's not always in one direction.
Yes, being busy is an excellent excuse to behave a bit like an Aspie, even if you're neurotypical.
Aspies (and introverts in general) thrive in environments where people are evaluated more on the basis of getting shit done quickly and accurately, and less on the basis of how often they drink with their boss. It's maker's schedule vs. manager's schedule all over again.
So, in a sense, modern societies' increasing emphasis on efficiency and productivity might work in favor of Aspies. So does urbanization, which allows you to disregard what your great-aunt's second cousin thinks about your new socks.
