Skills

AI-resilient: 2 of 5

  • Yes: Physical, lab or field work · "laboratory"
  • No: Live work with people
  • Yes: Judgment someone is accountable for · "diagnostics"
  • No: A craft you practice with your hands or body
  • No: Small, in-person format

The checks lean on Microsoft Research, Working with AI (2025), which found generative AI applies least to physical work and hands-on work with people. A signal, not a promise. How the score works
