Survives Durable: at least one of the four tests holds, and the evidence is direct.

Teachers

Real-time reading of other humans, in a room, with a duty of care.

Protection from automation: Well protected · our reading

The indivisibility argument is the strongest defence of a whole class of roles. Occupations are not lists of tasks; they are bundles, and some of them cannot be split — the argument McKinsey makes with the principal and the medical director.McKinsey 2025

Automating the individual activities (planning, marking, reporting) changes the job’s texture without removing the seat. What survives is the part that needs a person in the room making judgement calls in real time.

What holds it up

A teacher reads the room continuously and changes plan mid-sentence
Parents and institutions require a responsible adult in the building
The role is indivisible: every school still needs the seat filled

What threatens it

Lesson prep, marking and reporting are all being automated around the role
Clickwork tutoring products compete at the margins of the job

The four tests

What protects this job

Four things that keep a job out of a machine's reach. Score them 0–3 and add them up: the higher the total, the harder the job is to automate.

Needs hands and a body — yes (yes)
A person is answerable — very much (very much)
It needs a relationship — very much (very much)
The role can't be split — very much (very much)

Most of these hold. A machine cannot do this work on its own, so the job keeps its shape.

Our reading of the job, not a measurement — the evidence is below.

Verified claims

McKinsey places teachers among occupations with lower disruption because the work depends heavily on physical presence, regulation and human interaction. McKinsey 2025
Occupations are bundles of interdependent activities, and some are indivisible — every school still requires a principal, every hospital a medical director. McKinsey 2025
