That the bottleneck moved. For fifteen years the scarce skill was producing working code. This year my code output roughly tripled and my review and verification load more than tripled. The people around me who actually got faster did not have better prompting tricks, they had better taste in what to verify and the discipline to delete work that was plausible but wrong.

Smaller second lesson: writing things down got more valuable, not less. Specs, invariants, one page designs. The clearer the written thinking, the better everything downstream performs, humans included.
