A forecast, not a guarantee; occupation-level, not about you - and BLS does not model rapid AI adoption, so this is never an AI prediction.

How AI shows up in the work

Descriptive usage, not demand or loss

For this O*NET detail, the May 2026 usage sample reports 36.25% of Claude conversations augmenting the person's work and 63.75% automating a task. Anthropic · checked Anthropic Economic Index dataset, CC-BY.

Across all occupations the same dataset splits 51.4% augmentation / 48.6% automation (May 2026) — shown so a single role’s number is never read as an outlier.
