We develop a measurement framework from job postings in 2010 and 2018, constructing aligned skill spaces for 514 occupations covering over 75% of U.S. employment. Two geometric dimensions reveal three distinct processes: cognitive distance, scaffolded learning, and simplification. The qualitative nature of skill change determines worker outcomes, not magnitude alone.
