Dietitian vs Physical Therapist: which is more exposed to AI?
A 16-point gap separates these roles — Physical Therapist is the more defensible seat.
Dietitian sits at 40% time-weighted AI exposure against 24% for Physical Therapist, a 16-point gap driven by the 30% of dietitian work time that current models can already substitute outright. Physical Therapist holds a larger human-critical core — 78% of the role's time sits in work like "perform manual therapy and manipulation" that models score poorly on. Both roles sit inside Healthcare, so the exposure difference reflects task design rather than a change of field.
Seven dimensions, side by side.
What actually creates the gap.

The single largest contributor is "create education handouts", graded at 82% and worth 6% of the role's time. That one task accounts for more of the gap than any difference in seniority, tooling, or industry.
