Constitutive vs. Adjustment

In the AI Story

The Newtonian tradition treats all choices as adjustments. Given enough information about the current state of the universe, the future is determinate. Human choices are real in the sense that they occur, but they are determined by prior causes, and the trajectory they produce could not have been otherwise. The sensation of deliberation is, in this picture, a complicated consequence of physical processes rather than an operation with independent causal weight. The future that results from any choice is the future that was going to result regardless, because the choice itself was determined by the prior state.

Smolin's framework denies this comprehensively. If time is real and the future is genuinely open, then choices made in the thick present are constitutive of the future they produce. The choice does not select among preexisting futures; it creates the future that becomes actual. The alternative not chosen was not a hidden reality in some parallel branch; it was a possibility that the choice did not actualize. The trajectory the system follows exists because the choice was made. Without the choice, the trajectory did not exist.

The implication for the AI transition is the core move of Segal's foreword to the Smolin volume. If Smolin is right, then the dams being built now — the governance frameworks, the educational norms, the organizational practices — are not adjustments to a predetermined AI trajectory. They are constitutive of a trajectory that did not exist before they were built. The EU AI Act is not a course correction. It is the opening of a path through a landscape that did not previously have paths. The same is true of every other institutional precedent being established now. What looks like modulation is in fact creation.

This reframing transforms what it means to build responsibly. Under the adjustment framework, the builder's question is: how can I optimize the trajectory we are already on? Under the constitutive framework, the builder's question is: what trajectory do I create by building this, and what trajectory do I foreclose? The second question has greater moral weight because its consequences propagate further. A trajectory that did not exist before the building began, and that shapes what becomes possible afterward, is a trajectory the builder bears responsibility for having brought into being.

The distinction also illuminates the role of the silent middle in the AI discourse. Under the adjustment framework, the silent middle's hesitation looks like failure to commit to a position — a weakness in a world of strong opinions. Under the constitutive framework, the silent middle's willingness to sit with not-knowing looks like epistemic responsibility — the recognition that constitutive choices should not be made under conditions of false certainty, because the precedents they establish will outlast the certainty they were made with.

Origin

The distinction between constitutive and adjustment choices is developed implicitly throughout Smolin's temporal work and made explicit in his collaborations on the principle of precedence. Segal's foreword to the Smolin volume is, so far as this cycle's documentation reveals, the most precise articulation of what the distinction means for institutional and personal practice in the AI transition.

Key Ideas

Two possible relationships to the future. Choices either adjust a predetermined trajectory or create a trajectory that did not previously exist.

Framework determines stakes. Under adjustment framing, choices are optimizations within a fixed landscape; under constitutive framing, choices are creations of landscapes.

Physics selects the framing. Block universe requires adjustment framing; temporal naturalism permits constitutive framing.

AI transition as test case. The dams being built now are either course corrections (adjustment) or cosmological acts (constitutive) — the difference matters for how they should be approached.

Moral weight scales accordingly. Constitutive choices carry greater moral weight because they bring trajectories into existence that would not have existed otherwise.
