Physicists and astronomers
Moderate displacement risk
Composite of 5 dimensions (higher = more displacement pressure)
AI Exposure Analysis
Physicists and astronomers perform high-level knowledge work that is increasingly digital, including data analysis, mathematical modeling, and software development. While AI significantly accelerates data processing and literature review, the core requirements of original theoretical innovation, experimental design, and complex physical-world problem solving provide a buffer against full automation.
Dimension Breakdown
How many of this occupation's tasks can current or near-term AI systems perform? Based on GPT-scored analysis of 342 BLS occupations validated against 6 academic exposure indices.
How quickly will firms in this sector actually deploy AI? Accounts for regulatory burden, digital maturity, competitive pressure, union density, and organizational complexity.
How well can workers in this group transition to new roles? Composite of net liquid wealth (financial buffer), skill transferability, geographic job density, and age demographics.
When AI makes this sector's output cheaper, does demand expand enough to offset job losses? High elasticity means the Jevons Paradox may preserve or even grow employment.
Is AI primarily enhancing workers in this occupation or replacing them? Based on CFO survey data where available, estimated from task composition and job dimensionality otherwise. Jobs with more distinct task clusters (high dimensionality) tend toward augmentation via the O-Ring "focus effect" — automating some tasks lets workers concentrate on remaining ones, multiplying output quality.

Methodology
This page combines Karpathy's GPT-scored technical exposure (per-occupation) with four additional dimensions inherited from the parent SOC major group: institutional adoption speed, worker adaptability, demand elasticity, and AI complementarity.
Task composition is derived from O*NET work activity data, mapped to 8 internal categories. The complementarity score is adjusted by job dimensionality (Gans & Goldfarb 2024): occupations with more distinct task clusters tend toward augmentation rather than replacement.
Net displacement risk is computed as a weighted composite: exposure (30%), adoption speed (20%), adaptability (15%), demand elasticity (15%), complementarity (20%). Pressure dimensions are normalized independently from absorption dimensions, so defensive factors can fully counterbalance exposure.
