impact of automation technology and large language models on low-skilled workers

Source article: From automation technology to generative AI: skill heterogeneity in technology’s impact on laborers

Abstract This is a study of skill heterogeneity in technology’s impact on laborers transitioning from physical automation to cognitive automation. The findings indicate that cognitive skills are a crucial determinant of the extent of technological influence. Considering both technological substitution and technological control, high-skilled and low-skilled workers experience limited technological substitution. However, high-skilled workers are not significantly affected by technological control, whereas low-skil…

The quick read

A peer-reviewed study published November 17, 2025 analyzed skill heterogeneity as technology moves from physical automation to cognitive automation. It assessed both substitution and control, finding limited substitution for high- and low-skilled workers, but stronger control for low-skilled workers, and compared sectoral effects of automation versus large language models.

The findings matter because they suggest the new AI wave does not uniformly displace workers but reshapes control and concentrates LLM exposure in tertiary jobs and among women, younger workers, professional skilled laborers, and higher-income groups. Uncertainty remains about how substitution and control are measured and whether patterns persist beyond the studied context.

Main points
  • Study examines skill heterogeneity transitioning from physical automation to cognitive automation.
  • Cognitive skills are identified as a crucial determinant of the extent of technological influence.
  • Automation technology primarily affects the secondary sector, while large language models mainly affect the tertiary industry.
  • LLMs disproportionately influence women, younger demographics, professional skilled laborers, and higher-income groups.
Gain

High-skilled and low-skilled workers experience limited technological substitution from physical automation to cognitive automation, and high-skilled workers are not significantly affected by technological control.

Problem

Low-skilled workers are subjected to stronger technological control, and large language models disproportionately influence women, younger demographics, professional skilled laborers, and higher-income groups in the tertiary industry.

The rundown

The study frames impact through two mechanisms, technological substitution and technological control, and finds cognitive skills determine exposure.

It contrasts automation technology affecting the secondary sector with LLMs affecting the tertiary industry, with differential effects by gender, age, skill type, and income.
