My personal experiences have led to a waning sympathy for coworkers complaining about too many meetings or interruptions. It's a reactive complaint. The most productive engineers on my teams also tend to be the most disciplined in managing their tasks, guarding their calendars, and employing every Do Not Disturb option available.
To be honest, I think for a lot of developers the premise is already pretty flattering. I'd love to see a presentation titled: "You Were Not That Productive To Begin With, or Why That Fortnite Stream on Your Second Monitor Might Not Be Helping Things."
