The people-arc articles (A104, A110, A112) describe a squeeze from both ends: **careers are getting longer while the half-life of a skill collapses.**

- **A110** frames the macro: the [[concept-50-60-year-career|50–60-year career]] produces [[claim-midcareer-burnout-peak|burnout that peaks in the pivotal 40s]] — a [[claim-systemic-cohort-burnout|systemic cohort failure, not an individual weakness]] ([[quote-gratton-systemic-cohort]]). The dominant question shifts to [[claim-identity-over-performance|identity, not performance]].
- **A112** supplies the accelerant: [[quote-skill-devaluation|a skill can be devalued in a single product cycle]], which is why the [[contrarian-skills-based-obsolescence|static skills catalogue is already obsolete]] and continuous reskilling is mandatory.
- **A104** supplies a second stressor: [[concept-change-induced-burnout|change-induced burnout]] driven by priority whiplash, plus [[concept-identity-confusion|AI-induced identity fear]].

**The synthesis:** the same worker is being told (A110) her career is twice as long, (A112) her skills expire faster than ever, and (A104) her professional identity is threatened by the very tools deployed to help. The prescriptions rhyme — A110's [[framework-midcareer-recalibration|Reflect→Stretch→Explore→Move]], A112's [[concept-in-workflow-coaching|in-workflow coaching]], A104's [[concept-continuous-change-adaptation|normalizing discomfort]] — all reframe *movement and learning as reinvestment, not failure*.
