TL;DR:<\/strong> A skill is not a permanent asset \u2014 it depreciates, and different skills depreciate at wildly different rates. IBM puts the average half-life of a workplace skill at roughly five years, and a technical skill at about two and a half; the World Economic Forum’s Future of Jobs Report 2025<\/em> estimates 39% of core skills will be transformed or outdated by 2030<\/strong>, and LinkedIn projects that about 70% of the skills used in most jobs will change by 2030<\/strong>. But an average hides the whole game. This article reframes skills the way a CEO reads a depreciation schedule: some assets are consumables that expire in 12\u201324 months (a specific tool, a model’s prompt tricks, a platform tactic), some are durable for a decade (statistical reasoning, writing, systems thinking), and a few actually appreciate<\/em> with use (judgment, learning-how-to-learn, trust). The core asset here is an original Skill Half-Life Map<\/strong> that sorts 22 skill categories into five bands, each with its decay driver and compounding potential. From it falls a simple barbell strategy<\/strong> \u2014 keep relearning the fast-decaying layer on purpose while overweighting the compounding layer \u2014 and a ten-minute quarterly skill audit<\/strong> to keep your portfolio rebalanced. The CEO+Student move: allocate your learning capital like a CEO reading depreciation, and keep relearning the perishable layer like a student who never assumes the exam is over.<\/p>\n<\/blockquote>\n

A finance team never treats every asset as if it lasts forever. A laptop depreciates over three years, a building over thirty, and a strong brand can appreciate indefinitely. You fund each one differently because<\/em> their schedules differ. Most people manage their skills with no such schedule at all. They learn a tool, assume it is “knowing the field,” and are quietly surprised three years later when the thing they mastered is half-obsolete and the colleague who invested in the durable layer has pulled ahead.<\/p>\n

In the AI era this is no longer a slow background problem; it is the central one. When machines absorb the most perishable, codifiable skills fastest, the question stops being “what should I learn?”<\/em> and becomes “what should I learn given how fast it will decay?”<\/em> That is the CEO+Student question: lead your own development like a CEO who reads a depreciation schedule before allocating capital, and keep learning like a student who knows the syllabus is rewritten every year. Below is what the evidence says about how fast skills are decaying, an original map of which skills decay fast and which compound, and a practical way to allocate your learning accordingly.<\/p>\n
