> I do not dislike Slack as much as people assume given that I wrote a book titled “Deep Work,” which advocates for the importance of long, undistracted stretches of work. This marks the author out as a fantasist. Once a company gets above a couple of hundred employees, the majority of the new employees simply are not the sort of people who do "long, undistracted stretches of work". You can't carry on for ever hiring people who both have that sort of mentality and intellectual fortitude, and also want their job to completely dominate their day rather than just 9-5.
