What this score means

Most of this role's work is still genuinely hard for AI to do. Physical presence, bodily skill, high-context judgment, direct human care - the things that don't translate to text.

If you're in this role, here's what to do now

You're not in the firing line today. But the frontier moves. Build enough AI fluency now that you can direct it for the parts of your work that could benefit. People in unexposed roles who understand AI become unusually valuable inside their organisations.

The tasks in this role, ranked by AI exposure

Below are the real tasks O*NET records for this occupation, sorted highest exposure first. "AI can do this" means a language model can already handle the task directly. "AI can help" means an LLM can assist but not replace. "Human work" means today's AI doesn't touch it. Importance is O*NET's 1–5 rating of how central each task is to the role.

1 of 30 tasks in this role are things an AI can already do today. Task list mapped via O*NET "Automotive Service Technicians and Mechanics" (49-3023.00).

Where a project with Alex usually starts for this role

This role's strict α score is low because its top tasks are judgment, not drafting. But those same tasks compress dramatically when AI is paired with the right context and tools. The three highest-stakes tasks below are usually where we start.

  1. Inspect vehicles for damage and record findings so that necessary repairs can be made.

    O*NET importance 4.6/5 · strict α=0 (judgment-heavy) but compresses with tools

  2. Test drive vehicles and test components and systems, using equipment such as infrared engine analyzers, compression gauges, and computerized diagnostic devices.

    O*NET importance 4.4/5 · strict α=0 (judgment-heavy) but compresses with tools

  3. Test and adjust repaired systems to meet manufacturers' performance specifications.

Methodology

This role's exposure score comes from Eloundou et al's 2023 GPT task labels, aggregated by O*NET importance within each O*NET-SOC code, then bridged to UK SOC 2020 via ISCO-08 (ONS Vol 2 coding index) and US SOC 2010 (BLS crosswalk). Employment and median pay come from ONS ASHE Table 14.7a, 2025 provisional. ASHE covers employees only, so self-employed workers are not counted.
