Plumber (Journey-Level) vs Pneumatic Systems Technician (Mid-Level)
How do Plumber (Journey-Level) and Pneumatic Systems Technician (Mid-Level) compare on AI displacement risk? Plumber (Journey-Level) scores 81.4/100 (GREEN (Stable)) while Pneumatic Systems Technician (Mid-Level) scores 61.0/100 (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.
Pneumatic Systems Technician (Mid-Level): Core work is hands-on maintenance, repair, and troubleshooting of compressed air systems in unstructured industrial environments — protected by Moravec's Paradox, strong physical barriers, and growing demand from an aging workforce. Safe for 10+ years.

Sub-Score Breakdown
Plumber (Journey-Level) wins 5 of 5 dimensions — stronger on Task Resistance, Evidence Calibration, Barriers to Entry, Protective Principles, AI Growth Correlation.
| Dimension | Plumber (Journey-Level) | Pneumatic Systems Technician (Mid-Level) |
|---|---|---|
| Task Resistance (/5) | 4.1 | 4 |
| Evidence Calibration (/10) | 10 | 5 |
| Barriers to Entry (/10) | 8 | 6 |
| Protective Principles (/9) | 6 | 4 |
| AI Growth Correlation (/2) | 1 | 0 |
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 Pneumatic Systems Technician (Mid-Level) role pages.
