Every one of these effects lands on an individual, and none of them stays there. When a whole leadership layer anchors on the same first draft, accepts the same fluent answer and stops arguing with the frame, the organisation begins to decide the plausible thing. So does the market, because your competitors are asking similar models similar questions and getting similar answers back.
Convergence is the quiet cost. What erodes is the ability to arrive somewhere nobody else arrived, and that is your differentiation, then your innovation rate, then your competitive position. Sovereign use, practised by a leadership team rather than by scattered individuals, is what protects the difference.
