Most exposed

Where AI can do more

Routine, digitized, and highly repeatable tasks face the greatest pressure.

  1. Record and report time, materials, faults, deficiencies, or other unusual occurrences on work orders.67
  2. Adjust system controls to settings recommended by manufacturer to balance system.67
  3. Test electrical circuits or components for continuity, using electrical test equipment.66
  4. Connect heating or air conditioning equipment to fuel, water, or refrigerant source to form complete circuit.66
Hardest to automate

Where people still matter

These tasks score lowest on automation feasibility—physical presence, judgement, accountability and real-world variability all resist end-to-end automation.

Beyond AI capability

Adoption and labour-market outlook

Structural factors are kept separate from raw capability so you can see what actually resists automation. Adoption pressure and labour-market resilience are still provisional models—25% of this occupation’s replacement-risk weight rests on them.
