Context switches are not free.

Dozens of "quick questions" over the course of a day will drag down your productivity to about one third or worse.

I know that for me, it takes about 45 minutes of focus to enter a flow state, when I'm at my most productive. If I can never enter the zone, then I'm not really doing the thing that made me such a valuable player in the first place, am I?

He scheduled a call specifically to ask this question. What does context switching have to do with anything? Don't accept the call if you can't afford to switch context.

I wish I was there with you to witness the look on your face as you slowly begin to realize that something as simple as a call can and often will absolutely pull you out of the flow state.

Someone sneezing nearby can pull you out of the flow state.

The idea that the onus is on the person who you're trying to distract to distract themselves to tell you not to distract them is just so broken if you think about it even just a little bit.
