Milestone (age 25)

Created the NEST Network Simulator at Columbia University, which was distributed to over 150 sites worldwide by 1987 and presented at the Winter USENIX Conference in February 1988; it became the basis for subsequent network simulators including Cornell's REAL and LBL's ns simulator.

David Bacon began working as a programmer at age 16 and worked for a startup during his senior year of high school. At Columbia College, Columbia University, he worked with David E. Shaw on the NON-VON supercomputer and then with Yechiam Yemini on network algorithms, creating the NEST Network Simulator. He received his A.B. from Columbia in 1985 and started at IBM's Thomas J. Watson Research Center the same year, working on the Hermes distributed programming language.

Question four · where did the leverage come from?

David F. Bacon'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 David F. Bacon'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 Researchers / independent engineers, David F. Bacon's starting-advantage total is at the 74th percentile. Separately, their built or converted leverage total is at the 19th percentile. Other T3 profiles average 7.0 / 24 starting advantage and 11.7 / 25 leverage. Similar scores appear in other tiers, so these figures describe positioning—not a cause.

Evidence summary

David Bacon began programming at age 16 and worked for a startup during high school. At Columbia University, he worked with David E. Shaw on the NON-VON supercomputer and with Yechiam Yemini to create the NEST Network Simulator, which was distributed to over 150 sites by 1987 and became the basis for other major network simulators. He joined IBM's Watson Research Center in 1985 at age 22, placing him at the frontier of distributed systems research by his mid-20s. His early advantages were primarily institutional: access to Columbia's computing research environment and IBM's research lab.
