AI companies fail to explain what current models actually do; massive practitioner knowledge gap exists.

Underscores why hands-on builders outpace vendor docs—direct incentive to test, probe, and ship working setups yourself.

GPT 5.6 ported 15-year-old Python 2.x codebase to modern Python/libs without migration tools—upends old lessons.

Shows agent capability leap: old expertise (2.x→3.x patterns) now obsolete—signals a shift in what humans must manually optimize for.
