Constitutive vs. Adjustment
The structural distinction between choices that <em>create the trajectory</em> a system follows and choices that merely modify a trajectory already determined — the distinction that determines whether the dams we build now have cosmological weight or merely local effect.
Constitutive choices create the future they produce. Adjustment choices modify a future that was already going to happen. The distinction is not pragmatic but ontological. In the block universe — where past, present, and future coexist as a frozen four-dimensional geometry — all choices are adjustments, because the trajectory is predetermined and the only variable is how fast or slow the system moves along it. In Smolin's temporal naturalism — where time is real and the future is genuinely open — choices can be constitutive, because the trajectory is not predetermined and the choices made during moments of genuine novelty establish precedents that shape everything downstream. This distinction is, for Edo Segal, the most consequential gift Smolin's physics offers to You On AI's argument.

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
