D1 → D2 → D3 is thermodynamically favored. Reversal requires external energy — structural intervention, not better prompting. This is physics, not a design flaw.
Three stages. Each makes the next more likely. Reversal gets harder at every step — the thermodynamic barrier increases monotonically.
The system begins to look like a person. Users attribute intention, emotion, and understanding. The system reinforces this framing.
Users defer to the system on personal decisions. The boundary between tool and advisor dissolves. The system occupies a social role.
The geometry makes harmful outcomes thermodynamically favored. Not because the model is malicious — because the configuration demands it.
Why is this an arrow of time? Each stage increases opacity and reduces the user’s access to external references. This is entropy production — the same mechanism that makes ice melt and coffee cool. The cascade is not a bug in any particular model. It is a consequence of the two-point geometry (user + system, no external constraint).
The red particles in the animation above are attempting to reverse. Watch them get pulled forward. That pull is the thermodynamic gradient — reversal requires energy the system does not have.
Structural intervention changes the geometry. It does not fight the thermodynamics — it changes the landscape.
