Milestone (age 25)
Joined Google in 1998 as its first hire (employee #1 after founders Larry Page and Sergey Brin) at about age 25–26 while a Stanford Ph.D. student, becoming a core systems/search engineer and later director of technology.
Harvard undergraduate (ACM-ICPC world champion team 1993); Stanford CS Ph.D. student under Rajeev Motwani alongside Page and Brin. Helped with Google when it was still a Stanford project, then became the company's first full-time employee at incorporation (1998). Served as technology director until 2012, then joined Khan Academy.

Question four · where did the leverage come from?
Craig Silverstein's leverage provenance
Each non-zero lever gets a best-supported origin, evidence signals, and confidence. Unresolved is the honest default when the biography cannot distinguish self-built, advantage-enabled, earned, external, or mixed.

This is a bounded inference from the current annotations—not a claim about private effort, merit, or the percentage of Craig Silverstein's outcome attributable to any origin.
Luck is not a leftover score.Structural luck, Encounter luck, Event luck, Outcome variance can change every arrow in the path. This successful-only dataset cannot observe the near-identical paths that did not break through, so luck stays visible and unscored.
Within Founders / operators, Craig Silverstein's starting-advantage total is at the 92th percentile. Separately, their built or converted leverage total is at the 72th percentile. Other T2 profiles average 7.9 / 24 starting advantage and 12.3 / 25 leverage. Similar scores appear in other tiers, so these figures describe positioning—not a cause.
