I disagree. Humans still learn to read despite other humans reading at an objectively higher level since the beginning of writing.

Learning is not an output-efficient process but is a fantastic outcome. AI lowers some portions of the development workflow but not yet every part, and, efficiently produced outputs aren't always the major outcome desired. In the real world / outside the benchmark lab, you care about robustness, reusability, composability, security, and more. Targeting speed to acceptable average output inferred from a prompt or similar benchmark metrics miss a big part of the game.
