A networking equipment maker whose filing states 9,080 employees by region and role group but nothing by segment, so the equipment pattern leads by description with the services segment read apart by revenue.
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: 22% now, 43% at the end of 2027, 54% at the end of 2028, 59% at the end of 2030. By the patterns, the work is about 59% desk work, 19% people work and 22% 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 41% of the working time stays with people (conversation, in-person and hands-on work), 46% 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.
