The dream of Slack is that they become the central nervous system for all of a company’s employees and apps. This is the view of a clean *separation* of productivity and collaboration. Have all your apps for productivity and then have a single app for coordinating everyone, with your apps also feeding notifications into this system. In this way, Slack would become a star. With every app revolving around it. Employees would work out of Slack, periodically moving to whichever app they were needed in, before returning to Slack. But productivity *isn’t* separate from collaboration. They are the two parts of the same loop of producing work. And if anything collaboration is in *service* of team productivity.
The vision of Slack, according to Kwok, was for people to have their productivity in designated apps, and have one central nervous system (Slack) through which they could collaborate. This was based on the assumption that producing and collaborating could be separated.
Kwok claims that this assumption is wrong. Collaboration and productivity are intertwined, and you might event say that collaboration serves productivity.
