Ships’ deck crews and related workers
5.7%
ADI · 386th of 433 · 95% interval 0.0–13.6
An AI agent can at least partly carry out 5.7% of the task time of ships’ deck crews and related workers, and finish 0.0% alone. The barrier that holds most of the rest back is access to the systems the work runs on.
