A common scenario holds that AI raises output enormously while labor's share of income collapses, requiring massive redistribution. The author runs the numbers and concludes this is probably incorrect. Labor income is GDP times labor's share; a smaller share of a much larger economy can still mean more income for labor. If AI raises growth to 5 percent annually, labor's share can fall from 60 to about 45 percent with no loss in aggregate labor income; at 10 percent growth, it can fall to 28 percent. Three stylized views are considered: econ-pessimist (2.1 percent growth, 56.6 percent share, 2.7 percent transfer), econ-optimist (4.1 percent growth, 51.4 percent share, no transfer), and techno-optimist (10 percent growth, 22.9 percent share, 5.3 percent transfer). Labor's share alone tells us surprisingly little; growth matters too.
