The Turk Goes Quiet

  Copyright: Sanjay Basu Why Amazon Really Shut Down Mechanical Turk On September 30, 2026, Amazon Mechanical Turk, the crowdsourcing marketplace Jeff Bezos once called "artificial artificial intelligence", closed for good after 21 years. The irony is hard to miss. A platform built to hand machines the work they couldn't do was retired just as machines became good at much of that work, and as the people training frontier AI moved on to a different kind of labor market. Amazon's official explanation was one sentence long: "We regularly evaluate our programs, tools and services and make adjustments based on those assessments. Following an assessment, we've made the decision to close AWS Mechanical Turk, effective September 30, 2026". The company gave no usage figures, no migration path, and no successor. So the real reasons have to be pieced together from the timeline, from people who worked on the platform, and from where the market went. My reading is th...

Ninety One Percent Not Rubens

  A museum discovers its beloved masterpiece is a flawless forgery. Nothing on the canvas changes. The thing the visitors lost was never on the canvas, and the machines we built to keep it safe cannot hold it either. Two canvases, the same brushwork, opposite receptions. The wires run to the placards, not to the paint. In November 1937 Abraham Bredius, the most respected Vermeer scholar alive and seventy-nine years old, published a notice in The Burlington Magazine about a painting shown to him in Monte Carlo. It was a wonderful moment in the life of a lover of art, he wrote, to be confronted with a hitherto unknown work by a great master, and he was inclined to call this one the masterpiece of Johannes Vermeer of Delft. The painting was The Supper at Emmaus. Museum Boijmans in Rotterdam bought it that year for a figure usually given as 520,000 guilders, raised from the Rembrandt Society, the shipowner W. van der Vorm, several Rotterdam collectors, and Bredius himself. In 1945 a pa...

Bose, Schrödinger, and the Determinism Debate

  Copyright: Sanjay Basu Gained knowledge, lost faith: S. N. Bose, Schrödinger, and the 1944 determinism debate In October 2026, a physics historian in Geneva, Flavio Del Santo, published three handwritten pages that had sat in the Schrödinger Archive in Vienna for more than 80 years. The title on the first page was "Collapse of Determinism." Most of the coverage ran it as a lost manuscript with a twist. Schrödinger, the man usually filed next to Einstein, had built a hidden-variable model. That is the kind of thing a determinist builds. The twist that caught me sits a few paragraphs further into Del Santo's paper. He names the two talks that restarted the determinism debate in the 1940s. One was E. T. Whittaker's Guthrie Lecture in London in May 1943. The other was Satyendra Nath Bose's presidential address to the Indian Science Congress in Delhi on 3 January 1944. A report on Bose's address ran in Nature in July 1944 under the same title Schrödinger later us...
