Plumber

The clearest illustration of Moravec's paradox on the site. The reasoning is easy for a machine. The crawlspace is not.

Chapter four. The job that quietly outscores almost everyone reading this. Read the essay →

Resilience Anchored

Anchored by physical presence or by responsibility that cannot be handed over. Tools change; the job does not.

Scale, labels and thresholds are provisional. This is open question Q-02.

How the score is made

Four declared inputs, never collapsed into one number. Assistance is kept apart from outright automation, because a tool that makes you faster and a tool that replaces you are not the same event. Physical work counts as shelter only to the extent robotics cannot reach it.

The full method is written out, including what it cannot tell you.

Note on this occupation Physical exposure is high, but robotics readiness for unstructured domestic environments is low. That gap is the whole story, and it is exactly the gap Q-01 has to measure honestly.

Assisted
22

Higher is generally good news. It means more of the work gets faster without the work going away.

Done outright
8

This is the number most people mean when they say exposure. It is kept separate from assistance on purpose.

Physical
88

Protective only for as long as robotics cannot reach it. Read this one next to the robotics number, never alone.

Robotics reach
12

Low reach turns physical work into shelter. High reach turns it into the main exposure.

What changes

Tasks moving to machines, in whole or in part.

  • Quoting, scheduling and parts ordering.
  • Diagnosing a fault from a description or a photograph.
  • Compliance paperwork and certification records.

What stays human

Tasks that need a person, and why.

  • Working in a space that was never designed to be worked in.
  • Deciding what is actually wrong when the symptom is three rooms away.
  • Being the person a stranger lets into their home at nine at night.

What's new

Work that did not exist in this job ten years ago.

  • Installing and maintaining heat pumps, greywater and metering systems.
  • Reading sensor data from systems that report their own faults.
  • Retrofit work driven by regulation rather than breakage.

These three lists are editorial commentary, written against task-level data but not generated from it (OCC-05). Treat them as the author's reading, not as output.
