Look at the tools your team collaborates in every day. The @mention. The comment thread. The approval chain. The shared doc with nine cursors blinking in it. The Monday standup where everyone says "no blockers" (but you know at least two people are definitely lying).
Every one of them was designed around the same assumption: everyone on the team is a real-life, human person.
That assumption held up for decades. Then AI arrived, and most of us did the obvious thing. We bolted it on. One person, one AI, one chat window, and a lot of copy-paste in between. Each of us got faster on our own, and the team around us barely changed. Optimizely's agentic experimentation report found the same pattern across 900 companies: AI's impact is stuck at the individual level.
Collaboration is only difficult when you don't have the right tools for it, and the tools we have were never built for this brand-new type of team.
