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 →
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
- Done outright
- 8
- Physical
- 88
- Robotics reach
- 12
Higher is generally good news. It means more of the work gets faster without the work going away.
This is the number most people mean when they say exposure. It is kept separate from assistance on purpose.
Protective only for as long as robotics cannot reach it. Read this one next to the robotics number, never alone.
Low reach turns physical work into shelter. High reach turns it into the main exposure.
