Text as UI success I believe is tied to how connected the related task is to the messaging tool you are in and how easy the platform makes it for the user.  There are a number of tasks that could be good text candidates in a slack interface such as project management, time calendaring, tools used by the slack team.  I think it&#x27;s silly to jump to the conclusion that text is the future of ui.  I would agree that text is making a come back for relevant tasks within popular messaging tools.
