GitHub study: engineer productivity rises 2.8% per 10% growth of local tech cluster
lemire · x · 2026-11-09
Daniel Lemire argues economies are downstream of tech culture: web access alone doesn't turn regions into tech hubs. An attached paper using 2015-2021 GitHub data finds individual productivity rises 2.8% with each 10% increase in the local software community cluster size, with causal evidence for physical-proximity spillovers. He asks whether AI will increase geographic diversity of tech talent.
