AlphaFold isn’t about AI - Michael Nielsen
Michael Nielsen argues that AlphaFold's success is primarily due to decades of experimental data collection rather than AI innovation. He emphasizes that the billions spent on obtaining protein structures through experimental methods like X-ray diffraction represents the majority of the achievement.
Summary
In this brief analysis, Michael Nielsen challenges the popular narrative that AlphaFold represents a triumph of artificial intelligence. He contends that the real foundation of AlphaFold's success lies in the Protein Data Bank and the extensive experimental work that preceded it. Nielsen points out that billions of dollars were invested over many decades to obtain approximately 180,000 protein structures through various experimental techniques including X-ray diffraction, NMR spectroscopy, and cryo-electron microscopy. According to Nielsen, AlphaFold's story is fundamentally one of data acquisition rather than AI breakthrough. He describes the process as decades of painstaking experimental observation of the world, followed by fitting an impressive model to that data - but emphasizes that the AI component, while impressive, represents only a small fraction of the total investment and effort. This perspective reframes AlphaFold not as an AI revolution, but as the culmination of extensive experimental scientific work with AI as the final, albeit sophisticated, analytical layer.

[0:00] Alpha really isn't about AI. A massive fraction of the success there is the protein data bank. So it's it's X-ray defraction, it's NMR, it's cryom, and the several billion dollars that was spent obtaining whatever it's 180,000 odd struct protein structures. It's basically the story of we spent many many decades obtaining protein structure just by going out and looking very hard at the world experimentally and then we fitted a nice model at the end of it and that was like a tiny fraction of the of the entire investment. But it's definitely not you know that's a story of data acquisition principally. It's [0:31] not only I mean the AI bit is very very impressive.

The Army Sent to Stop Cortés Joined Him Instead - Si Sheppard
Spanish conquistador Cortés faced a threat from Governor Velázquez of Cuba, who sent Don Narvaez with a larger force to arrest him for exceeding his authority. Rather than being defeated, Cortés defeated Narvaez in battle and persuaded the expeditionary force to join him by promising shared wealth from the empire, turning potential enemies into reinforcements.
How 168 Men Captured the Inca Emperor - Si Sheppard
Francisco Pizarro, with only 168 men, captured the Inca Emperor Atahualpa in 1532 at Cajamarca by using psychological tactics with horses and an ambush strategy. Despite Atahualpa's show of dominance and his large army, Pizarro's surprise attack and capture of the emperor allowed him to control the entire Inca social hierarchy.
The Myth of the Helpless Aztecs and Inca - Si Sheppard
Si Sheppard argues that the Aztecs and Incas were not helpless victims but actively developed countermeasures and adaptive strategies against Spanish conquistadors, including terrain manipulation, weapon improvisation, and tactical learning—though they lacked sufficient time to fully master foreign technologies.
How Conquistadors Conquered the Aztecs - Si Sheppard
Conquistador success against the Aztecs relied primarily on steel weapons, horses, and psychological tactics rather than firearms. Steel armor and swords proved far more effective than indigenous weapons made of wood, stone, and obsidian, while horses—animals unknown to the Aztecs—provided decisive military and logistical advantages.
How did a few hundred Spanish soldiers topple two empires? – Si Sheppard
Military historian Si Sheppard explains how a few hundred Spanish conquistadors were able to conquer the Aztec and Inca Empires within just a few years through a combination of technological advantages (horses, steel weapons), psychological warfare, diplomatic manipulation of existing divisions among indigenous peoples, and the catastrophic impact of disease. The conquests were contingent on individual leadership decisions and geographic factors, but were fundamentally enabled by the conquistadors' ability to exploit internal rifts within empires that appeared monolithic from the outside.
