Auto Mechanic vs Plumber: which is more exposed to AI?
Auto Mechanic carries 13 points more AI exposure than Plumber.
Auto Mechanic sits at 29% time-weighted AI exposure against 16% for Plumber, a 13-point gap driven by the 0% of auto mechanic work time that current models can already substitute outright. Plumber holds a larger human-critical core — 92% of the role's time sits in work like "install pipes, fixtures, and systems" that models score poorly on. Both roles sit inside Trades & Construction, so the exposure difference reflects task design rather than a change of field.
Seven dimensions, side by side.
What actually creates the gap.
Both roles hand a similar slice of the week to substitutable work — 0% for Auto Mechanics, 0% for Plumbers — but it is different work. Auto Mechanic exposure concentrates in "retrieve diagnostic codes and service info"; Plumber exposure concentrates in "read and interpret plumbing plans". Two roles can share a score and face completely different disruption timelines.

- Road test and validate repairs12% · 6% time
- Inspect vehicles and diagnose faults18% · 24% time
- Install pipes, fixtures, and systems4% · 36% time
- Diagnose and repair leaks and blockages12% · 28% time
- Inspect existing plumbing systems14% · 14% time
Both roles lean on manual, procedural, judgement — that is the part of your experience that travels intact. Beyond that, the two capability profiles are unusually close: no dimension separates them by more than 15 points, which is why the switch difficulty below reads the way it does.
Neither role lists the other as a mapped adjacent career, but the capability profiles are only 6 points apart on average and both sit in Trades & Construction. In practice that means a move is plausible without retraining from scratch — the constraint is credentials and hiring convention, not capability.

Is Auto Mechanic or Plumber more at risk from AI?
Auto Mechanic. It scores 29% time-weighted AI exposure against 16% for Plumber — a 13-point gap. 0% of auto mechanic work time is already fully substitutable by current models, versus 0% for Plumbers.
Which pays more, Auto Mechanic or Plumber?
Plumber, by roughly $13k at the median ($62k versus $49k). Note that the higher-paying role here is also the less AI-exposed one, which matters if you are weighing pay against durability.
Can a auto mechanic switch to being a plumber?
Neither role lists the other as a mapped adjacent career, but the capability profiles are only 6 points apart on average and both sit in Trades & Construction. In practice that means a move is plausible without retraining from scratch — the constraint is credentials and hiring convention, not capability.
Which role is growing faster, Auto Mechanic or Plumber?
Auto Mechanic, at 3% projected ten-year growth versus 2% — a 1-point difference. Growth and AI exposure are separate signals: a role can grow in headcount while the content of the work is substantially rewritten.
