The figures on this page come from the company's own annual report and from BLS staffing patterns for its industries, never from a roster. They are estimates with a stated method. Nothing here says what the company will do: within reach is not a forecast of jobs lost or of savings.

What follows from the reading

Share of working time within reach of AI, on the long-run pace at four in five: 39% now, 48% at the end of 2027, 51% at the end of 2028, 52% at the end of 2030. By the patterns, the work is about 52% desk work, 20% people work and 28% body work. These are the site's industry estimates weighted by the shares below: estimates with a stated method and range, not a forecast of what the company will do. By the same patterns, at the end of 2028 about 49% of the working time stays with people (conversation, in-person and hands-on work), 42% becomes checking a model's work and 7% could be handed over with lighter checks, from the industries' own figures, not the company's roles.
