Verdict
Bus and Truck Mechanics and Diesel Engine Specialists is the safer bet: it scores 16/100 against 20/100 for Geothermal Technicians — 4 points less exposed to AI.
Installation & Repair
16 /100
Diesel diagnostics increasingly use AI-assisted scanners, but hands-on repair of heavy mechanical systems remains firmly human.

20 /100
AI handles reporting and design calculations, but physical commissioning and field troubleshooting of geothermal systems stays human.

| Timeline | AI scan tools improve diagnosis speed now, but the wrench-turning and heavy-component work remains hands-on for at least a decade; electrification adds complexity rather than removing jobs. | Growing demand for geothermal as a clean energy source will expand this role; AI tools will accelerate design but field commissioning remains hands-on through 2035. |
