In front of him were three things: a half-empty cup of black coffee, a stack of engineering textbooks, and a smartphone glowing with a message from his mother: “Have you found a study group yet?”

Within 20 minutes, three different users had annotated the whiteboard. A student in Surabaya drew the contour. A teacher in Manila corrected a sign error. And a man in Taipei—who had once been that lonely student—added a final note in the margin:
