Plumber (Journey-Level) vs Theme Park Ride Technician (Mid-Level)
How do Plumber (Journey-Level) and Theme Park Ride Technician (Mid-Level) compare on AI displacement risk? Plumber (Journey-Level) scores 81.4/100 (GREEN (Stable)) while Theme Park Ride Technician (Mid-Level) scores 63.2/100 (GREEN (Stable)). Here's the full breakdown.
Plumber (Journey-Level): Near-maximum Green — every signal converges. Physical work in unstructured environments, licensing barriers, acute labour shortage, and AI infrastructure indirectly boosting demand. AI cannot fix a burst pipe behind a wall.
Theme Park Ride Technician (Mid-Level): Physically climbing roller coaster structures, servicing hydraulic launch systems, and diagnosing faults on bespoke ride hardware in extreme heights and confined spaces makes this role deeply protected by Moravec's Paradox. AI augments diagnostics and scheduling but cannot turn a wrench 200 feet up a coaster lift hill. Safe for 15+ years.

What Do These Scores Mean?
Each role is assessed using the AI Job Resistance Index (AIJRI), a composite score from 0 to 100 measuring how resistant a role is to AI displacement. The score is built from five dimensions: Task Resistance (how many core tasks can AI automate), Evidence Calibration (real-world adoption data), Barriers (regulatory, physical, and trust barriers protecting the role), Protective Principles (human-centric factors like empathy and judgement), and AI Growth Correlation (whether AI growth helps or hurts the role).
Roles scoring above 60 land in the Green Zone (AI-resistant), 40–60 in the Yellow Zone (needs adaptation), and below 40 in the Red Zone (high displacement risk). For full individual assessments, see the Plumber (Journey-Level) and Theme Park Ride Technician (Mid-Level) role pages.
