~30 years ago I sat down with two students and accused them of copying each others’ work, because they both made the same amusing mistake: they called their C functions without passing arguments, but they declared their variables in such a way that the values would coincidentally be in the right place on the stack. I have to imagine debugging their own code was a mystery.

They indicated that while they worked closely together while learning the material, they weren’t stealing from each other. I believed them then, and still believe them now, but I’m so glad I don’t have to deal with today’s AI world.
