Salvatore Sanfilippo argues the agent-era skill is Torvalds's, not the kernel author's

Summary: Salvatore Sanfilippo published a post on 2026-07-25, adapted from his own video, arguing that Linus Torvalds's rare contribution was not writing a Unix kernel for the 386, which he says perhaps one programmer in a thousand could have done, but stopping writing code early to hold the design direction and coordinate maintainers through review and dialogue. He proposes that skilled developers working with coding agents should take the same role, supplying architecture, design, and judgment while delegating implementation, and distinguishes this from prompting for code and accepting the output. He contrasts Torvalds with maintainers who keep implementing directly, naming his own Redis work and a recent linenoise pull request from SQLite's Richard Hipp as the small-codebase case where that still fits.
Why it matters: It reframes the agent-adoption question as a delegation problem with a known precedent rather than a prompting problem, which is the axis teams evaluating agent workflows keep missing.
