Yes, I have also heard that repeated ad nauseam. I think it is highly debatable and individual. I also think a lot of people overestimate how "deep" their own work is compared to others. E.g. a lot of programming is just tedious busywork and scaffolding, yet every programmer here seems to think a slight interruption is a destructive event. Maybe the problem is with you, not others. Maybe you are not a good match for working on a team. At many companies, plenty of programmers and engineers do complex, meaningful work in a crowded, very busy setting, with lots of talking over each other's heads. Have you seen how SpaceX or Tesla engineers work? What some people call deep work others do with their hands tied and constant "interruption".
