Reading this family

computed

The median installation, maintenance and repair occupation has 13.3% of its weighted task load in work current AI systems can already produce, which is 11.0 points below the median across every occupation in the index. Weighted by how many people actually do these jobs, the figure is 17.1%, across 6,076,810 US workers. 2 of these occupations fall in the exposed band, 0 in assisted and 48 in untouched.

What holds the line across this family is embodiment, at 2.49 out of 3, the highest of the five friction dimensions here. In plain terms the obstacle is a body in a place. The work happens to physical objects in physical rooms. No amount of model capability reaches it, because the bottleneck is hands rather than reasoning.

The spread inside the family is wider than the gap between families, which is the usual pattern and the reason this index does not publish a single number per group. First-Line Supervisors of Mechanics, Installers, and Repairers sits at 35.0%. Refractory Materials Repairers, Except Brickmasons sits at 0.0%. Both are installation, maintenance and repair occupations, and 35.0 points separate them.

Exposure is not displacement. These figures say what current systems can produce and what stands in the way. They do not say anyone will stop paying a person to do the work. How the score is built.
