The bottleneck was never the code

Brooks 1975: software is the residue of human negotiation. For 50 years, tooling investment kept attention on the residue; agents collapsed the residue cost and exposed the substrate. The bottleneck moves from coders to spec-producers, which is to say management. Every AI productivity claim now needs a denominator that is not engineer-coding speed but spec-to-shipped cycle time. If management bandwidth is the bottleneck, individual agent productivity gains compound at zero, and you have just bought yourself the world's most expensive feature-bloat machine.
