What lifts it above grievance is that the author has sat on the other side of the table — having had to justify and carry out earlier rounds — and declines to pretend the tools are useless: models are genuinely good at ported, measurable work where a human can checkpoint each step, and the piece cites Shopify's return to native mobile and a TypeScript-to-Rust port that faithfully reproduced the original's bugs. What they cannot do, the argument goes, is taste and foresight — saying no to the feature the complaint thread demands, and pricing in what a decision costs in operating complexity three years out. The detail that stays with you is not the argument but the body: a resting heart rate above 100, under four hours of sleep a night for more than a week, and a hiring manager laid off a week after interviewing the author.

An internal Anthropic research model, handed the problem cold, took under half an hour. Rather than hunt for the hash function everyone assumed was behind the seeds, it guessed the numbers were output from a weak random number generator of the period, noticed the top bit of every 32-bit word was zero across all four seeds — a 1-in-5,810 coincidence and the fingerprint of `lrand48` — brute-forced the hidden state for the binary curves and recovered it for the prime curves with lattice reduction. Run the recovered states back through `srand48` and you get Unix timestamps from 1997 and 1998: somebody sat there running a program in a loop until the curve came out valid, and P-256 was candidate number 1,842. The post ships Python that reproduces the published values and is candid about the loose ends — B-163 and most of the base points remain unexplained. Nothing here breaks ECDSA.

So the policing moved to the surface of things — Quintilian ruled on how a toga should hang and called one particular drape effeminate, the handbooks warned against a shrill voice, and Cicero wanted gestures borrowed from the wrestling ground rather than the stage, because an actor's hands were a slave's hands.
