What this score means.

Most of this role's work is still hard for AI: physical presence, practised skill, judgement in context and direct care, the things that do not turn into text.

If you are in this role

Nothing here is under pressure today, but the frontier moves. Learn enough to direct AI at the paperwork around the job. People in hands-on roles who can do that become unusually useful inside their organisations.
