SAFE
The job is hands-on fine-motor work on another person's living hands and feet — shaping nails, pushing cuticles, removing calluses, applying and curing gel, sanitizing tools — none of which language models touch and none of which current robotics can do safely on a moving human. Licensing (state nail technician credential, sanitation rules) and repeat-client relationships add real protection; the automatable slice is scheduling, reminders, intake forms, and social-media marketing. The genuine threats to this occupation are cheap press-on and at-home gel products and wage competition, not AI.
Tasks largely resist digitisation. Filing a nail to a client's requested shape, pushing back a cuticle without drawing blood, judging when gel is cured enough to stop the lamp — these are tactile calibrations made in real time against a hand that flinches, and the only digitisable parts of the day are booking, deposits, and posting photos of your work, which is why this sits at 17 rather than mid-range.
Hands-on in uncontrolled environments. You are physically holding a stranger's foot, working around ingrown edges, fungus, diabetic skin, and calluses at close range with drills and nippers, in a salon with acetone fumes and clients who move — a 19 reflects that there is no version of this task that happens away from the body.
Licensed human required and personally liable. Every state but a handful requires an individual nail technician licence with training hours and a board exam, and sanitation violations or an infection traced to your implements land on your licence, not the salon's alone — an 11 rather than higher because the credential is a few hundred hours, not a scope-of-practice monopoly over a protected medical act.
The human relationship is the product. Regulars book you by name for a 45-minute conversation and hands they trust with a drill bit, and they follow you when you change salons — 14 not 18 because walk-in and discount-salon volume is real and a lot of clients are choosing price and location, not a person.
Executes defined procedures on defined inputs. The decisions are bounded — which shape, which product for a client's nail condition, when to refuse service on an infected nail and refer out — real calls, but made inside sanitation protocol and product instructions rather than in genuine ambiguity, which is what 6 marks.
