If tools are well-integrated and mentally compartmentalized (e.g., Slack for fast input, Notion for synthesis, Jira for logistics), switching shouldn't feel painful. But when decisions get scattered and nothing enforces consolidation, yeah, it becomes chaos by slow erosion.
Ironically, the more we try to unify everything into one tool, the worse the mental clutter gets. The problem isn't that we have too many tools, it's that we try to make each one do more than it's supposed to.
So, It's not app switching that kills productivity. It's app misusing.
