Where AI reaches the work
The job’s main tasks, heaviest first, by how far AI reaches them.
Within reach(3)
- Select and install blades, tools, or other attachments for each operation.
- Select coolants and lubricants, and start their flow.
- Inventory and record quantities of materials and finished products, requisitioning additional supplies as necessary.
Out of reach(26)
- Observe continuous operation of automatic machines to ensure that products meet specifications and to detect jams or malfunctions, making adjustments as necessary.
- Measure and visually inspect products for surface and dimension defects to ensure conformance to specifications, using precision measuring instruments.
- Turn valves and dials of machines to regulate pressure, temperature, and speed and feed rates, and to set cycle times.
- Read specifications, blueprints, and work orders to determine setups, temperatures, and time settings required to mold, form, or cast plastic materials, as well as to plan production sequences.
- Observe meters and gauges to verify and record temperatures, pressures, and press-cycle times.

What these numbers mean
The score is the share of this job’s work, weighted by how important and frequent each task is, that AI could do in half the time: tasks an AI model could do alone count in full, tasks that need software built on AI count half.
“AI already used” is the share of the work in tasks where people are recorded using AI today. “As AI tools mature” counts every task AI could halve, with or without extra software.
The percentile compares the score with every job’s, weighted by how many people in the US do each one. Exposure means AI could change how the work is done, not that the job goes away. These are estimates for the typical job, not predictions.
