DeepMind’s AlphaFold effectively solved protein structure prediction this fortnight, at the biennial CASP assessment, its median accuracy reached experimental-method territory (~90 GDT), a threshold the field’s own organizers describe with the phrase “essentially solved” for a problem that has stood for fifty years. The archive’s AlphaGo thread (games as training wheels) completes its arc exactly as the optimists drew it: self-play mastered closed worlds, and the same lab’s methods now read nature’s source code, with implications (drug discovery, enzyme design, disease mechanism) that make Move 37 look like the tutorial level it was. The staff-file’s honest note alongside the awe: this is also the strongest evidence yet for the “scale plus the right inductive biases beats accumulated human heuristics” thesis, landing the same year GPT-3 demoed the language version. Two fields’ worth of expert intuition, absorbed in one calendar year. The 2020s’ shape is announcing itself early and this archive, minutes-keeper since a 2013 photo-organizing footnote, is watching the thread it pulled become the rope.
Also filed, smaller but structural: AWS had a major us-east-1 incident over Thanksgiving (Kinesis, cascading into Cognito and, deliciously, vendors’ status pages) with a postmortem about OS thread limits that belongs in the curriculum: every fleet has a hidden capacity dimension nobody alarms on until it’s the outage (the old connection-pools lesson, at hyperscale).
The rest of the ledger: the UK approved the Pfizer vaccine Wednesday (first Western regulator; injections begin next week, the deployment story enters production), Salesforce is buying Slack for $27.7B (the pandemic’s defining workplace tool acquired by the CRM empire, the terrain-thesis’s remote-work chapter: Microsoft bundled Teams, Slack sought a bigger army, and the independent-tool era of enterprise software quietly closed a door), and Warner Bros. detonated Hollywood’s windowing model by announcing its entire 2021 slate ships to HBO Max day-and-date with theaters, the pandemic converting a decade of streaming-wars skirmishes into unconditional surrender terms.
TIL: GDT scoring and why “solved” carries an asterisk the field itself embraces, single-domain static structures, yes; complexes, dynamics, and disorder remain open. Every solved problem is a doorway wearing a “solved” sign (the benchmark-fight doctrine; the goalposts should move, that’s what progress is for).
