How is AI coding different for senior vs. junior developers?

Junior developers gain the most from AI for syntax help, boilerplate, and learning unfamiliar APIs — it accelerates the ramp-up period significantly. Senior developers use AI differently: as a force multiplier for tedious tasks (tests, docs, repetitive refactors), a second opinion on design decisions, and a way to explore unfamiliar languages quickly. Seniors also know when NOT to trust AI output, which is a critical skill.
