The Skill Shelf Life Problem

Technical skills now have a half-life of roughly five years. What you learned in college may be partly obsolete before you pay off your student loans. Programming languages rise and fall within a decade, so the safest bet is to keep learning.

This rapid obsolescence represents a fundamental shift. Previous generations could learn a trade and practice it for forty years. Today's workers must continuously update their skills throughout their careers, treating education as a lifelong process rather than a one-time event.
