Fibre preparing, spinning and winding machine operators
4.8%
ADI · 395th of 433 · 95% interval 0.0–14.8
An AI agent can at least partly carry out 4.8% of the task time of fibre preparing, spinning and winding machine operators, and finish 0.0% alone. The barrier that holds most of the rest back is access to the systems the work runs on.
