Simon Sinek
Confidence 0.75 · 2 sources · last confirmed 2026-06-20
Simon Sinek is a leadership author and speaker — the originator (in business vocabulary) of Start With Why (2009), Leaders Eat Last (2014), Together Is Better, and The Infinite Game (2019), and host of the podcast A Bit of Optimism. He describes himself as “an unshakable optimist.” The wiki promotes him from Dangling to an entity page on 2026-06-20 after the second substantive source: he is both the subject of the 2018 NYT keynote that previewed The Infinite Game and the host of the 2026 A Bit of Optimism episode with Ethan Mollick.
Role in the wiki
Sinek sits at two distinct points in the corpus:
-
The infinite-game framework. His 2018 NYT Events keynote (2018-05-31-sinek-nyt-the-infinite-game, ~25:48, 1.1M views) popularised James P. Carse’s finite-vs-infinite-game distinction for business — the load-bearing source for the wiki’s infinite-game concept and the finite-vs-infinite-game synthesis. The argument: business is an infinite game (no fixed players, changeable rules, no terminal state), but most leaders play it as if finite, producing the “quagmire” failure mode. (His 2019 book of the same name remains a deferred-ingest target that would lift the infinite-game concept’s confidence.)

Interviewer / platform. In [[2026-06-16-mollick-simon-sinek-ai-skills-experience-edge|A Bit of Optimism (June 2026)]] Sinek hosts Ethan Mollick for a wide-ranging conversation on AI, skills, taste, and agency — the channel that surfaced that source into the wiki’s durable-skills / jagged-frontier / ai-deskilling cluster. Here Sinek is the host/elicitor rather than the claim-maker; the substantive AI content is Mollick’s.
