Picture a surgeon mid-operation. The surgical team knows exactly what they are doing because of the briefing that happened right before the first incision. The patient's chart was reviewed, the approach was agreed on, the risks were flagged. Everyone is aligned. But then something unexpected happens two hours in, the team shifts, and by hour four, the people still in the room are working off a mix of current information and faded memory of things said at the start. The briefing is gone. The notes are somewhere else. And the decisions made at hour one are getting relitigated because nobody remembers what was settled.
That is a long AI conversation after about an hour of real work.
