Lime Plasterer (Mid-Level) vs Spray Foam Insulation Installer (Mid-Level)
How do Lime Plasterer (Mid-Level) and Spray Foam Insulation Installer (Mid-Level) compare on AI displacement risk? Lime Plasterer (Mid-Level) scores 78.0/100 (GREEN (Resilient)) while Spray Foam Insulation Installer (Mid-Level) scores 71.5/100 (GREEN (Stable)). Here's the full breakdown.
Lime Plasterer (Mid-Level): Heritage lime plastering is irreducibly physical, site-specific craft work on irreplaceable historic fabric where material science judgment, manual dexterity, and regulatory gatekeeping (listed building consent, conservation officer approval) combine to create deep AI resistance. Strong niche demand driven by a recognised UK skills gap and an ageing building stock that requires traditional materials by law.
Spray Foam Insulation Installer (Mid-Level): Solidly Green — spray foam application in confined, variable retrofit environments is peak Moravec's Paradox. Zero AI exposure observed. Green retrofit demand and workforce shortage reinforce long-term protection. Core spraying and chemical handling tasks remain irreducibly human for 15-25+ 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 Lime Plasterer (Mid-Level) and Spray Foam Insulation Installer (Mid-Level) role pages.
