Opinion: This incredible hospital robot is saving lives. Also, I hate it

The robot, I'm told, is on its way. Any minute now you'll see it. We can track them, you know. There's quite a few of them, so it's only a matter of time. Any minute now. Ah, and here it is. Far down the hospital hall, double doors part to reveal the automaton. There's no dramatic fog or lighting—which I jot down as "disappointing"—only a white, rectangular machine about four feet tall. It waits for the doors to fully part, then cautiously begins to roll toward us, going about as fast as a casual walk, emitting a soft beep every so often to let the humans around it know it's on a very important quest.
