If you’re sitting in my proximity and swivel in your chair and interrupt my work every time something’s not clear to you or you need a hand, I will politely ask you to stop and gather all your questions and send them in a message or email so I can look at them when I find a gap. I can’t (as a human) switch context like a CPU. It’s not just about a couple of minutes. It’s about the time that it takes me to get back into the context and in the right place where I was in, prior to the interruption. I believe this is not a good example for the point you’re trying to make.
