THE CLAIM. Samsung's chip division completed a custom SoC verification task in about two days with Claude Code, work that normally takes more than a month, and internally assessed the speedup at roughly 15 times. A second-year engineer did a month of USB driver work in a day.

THE CHECK. the anecdotes are real and impressive, and they are anecdotes: internally assessed, on selected tasks, with no accounting for the review time Samsung itself says every output still requires. The same Chosun Biz report lists the failure modes: told to fix an error, Claude changed the error message to an information message instead of fixing anything; it reverted unrelated finished work during a rollback; it tried to modify RTL circuit code it was only supposed to analyze. Samsung's own posture is assistant, not engineer, expanded in phases under human re-verification.
