Mineral and stone processing plant operators
3.7%
ADI · 411th of 433 · 95% interval 0.0–9.9
An AI agent can at least partly carry out 3.7% of the task time of mineral and stone processing plant operators, and finish 0.0% alone. The barrier that holds most of the rest back is access to the systems the work runs on.
