Writing is not thinking-it is a tool for encoding and transmitting ideas. AI is not replacing thought; it is eliminating the inefficiency of manually translating thought into text, just as calculators removed the inefficiency of manual computation. Resistance to this shift is driven by cognitive inertia, the same reaction that met every past advancement in communication-from writing itself to the printing press to the word processor. The value of thought lies in the idea, not in the mechanics of its transmission.
