For most of history, physical work was muscle. Then steam, combustion, and electric motors took it. Human muscle became a rounding error in the global energy budget. Cognitive work is on the same curve, compressed in time.

When the price of a scarce input collapses, supply floods and demand expands. Cheaper engines did not reduce coal use. They multiplied it. Cheaper cognition will not reduce thinking. It will multiply it. Most problems on Earth currently go unthought about because thinking is expensive.

The dominant narrative says AI will cause mass unemployment. Three years of real data say otherwise.

Over 90% of U.S. firms that adopted AI reported zero change in headcount. Multiple surveys from the Atlanta Fed, Census Bureau, and other sources show the same pattern: almost no net job loss. What is happening instead is task reallocation inside existing roles. Recruiters do less screening and more judgment work. Lawyers review AI output rather than draft from scratch. Finance teams interpret rather than assemble data.

Automation does not eliminate work. It reshapes and multiplies it.

The recurring pattern is the *Human Sandwich*: humans remain essential at the top (setting the frame, defining strategy and intent) and at the bottom (handling edge cases, exceptions, and final accountability), while AI takes over the repetitive middle layers. As AI capability advances, the middle layer expands and the sandwich gets thinner — but the human layers never disappear.
