The half-life of your skills may be as short as five years—and it’s only getting shorter.
The “half-life” of our skills—the period during which a skill retains half of its value—is shrinking fast. Once, a single skill set could support a career spanning decades. Today, especially in fields like technology and AI, skills can become obsolete within just a few years. According to an IBM study, the average half-life of technical skills is now only three to five years, underscoring the need for continuous learning to maintain relevance in an AI-dominated world.
The Half-Life of Skills: Why It’s Shrinking Faster Than Ever
The concept of a “half-life” traditionally refers to the time it takes for a substance or radiation to reduce by half, but it’s an apt metaphor for the life and relevance of hard-earned skills. Advances in technology, AI, and automation mean that skills are becoming outdated faster than ever.
AI models are becoming increasingly capable; for example, Anthropic’s recent “computer use” capability allows AI models to control a mouse and keyboard, browse the internet, and pull information from various applications. This breakthrough could enable AI agents to operate software applications independently. While the impact of generative AI and robotics may not be felt by all yet, it’s compounding rapidly, underscoring the speed with which our skills can be made redundant and the need for proactive skill-building.
Skills and Jobs Most at Risk
AI is becoming faster, smarter, and more efficient than humans at many tasks—a reality former Google executive Mo Gawdat discusses in Scary Smart (2021). Gawdat warns that AI is now capable of outperforming us in ways we may not yet fully grasp, pushing us to rethink which skills we should prioritise.
Some roles especially vulnerable to AI automation within five years include:
Basic Coding and Software Development: AI tools already handle routine coding tasks and bug fixes, automating entry-level development work.
Accounting and Financial Analysis: Automated software performs tasks like bookkeeping, tax preparation, and forecasting, reducing junior accounting roles.
Legal Research and Document Review: AI-driven systems efficiently review documents and analyse contracts, cutting down on basic legal research time.
Radiology and Medical Image Analysis: Algorithms can now analyse X-rays, ECGs, and MRIs, assisting with diagnostics and reducing demand for initial image reviews.
Market Research and Trend Analysis: AI monitors and analyses large datasets and consumer trends, providing automated insights without extensive manual input.
Customer Onboarding and Support in Banking: AI increasingly handles identity verification, support, and onboarding in financial services.
Warehouse Operations and Inventory Management: Robotics handle sorting, picking, and inventory management, with projections that robots will automate most tasks within ten years.
Quality Control and Inspection in Manufacturing: Automated systems with computer vision are replacing human inspectors in high-volume quality checks.
Human Resources and General Administration: Routine HR tasks like CV screening and scheduling are now handled by AI, with most administrative processes likely to be automated soon.
Translation and Transcription Services: Advances in AI now allow real-time, high-quality translations and transcriptions, affecting roles in language services.
Anthropic’s “computer use” feature allows AI to perform tasks traditionally done by humans, such as web browsing, application usage, and data entry. Additionally, robotics are advancing in dexterity and safety, with recent developments from Meta bringing robots closer to replicating human touch and precision.
As AI’s capabilities grow, the "cost of IQ"—or cognitive labour—continues to drop. Technical hurdles around AI’s abilities are being solved faster than anticipated, creating a new landscape where IQ is rapidly losing value, and even our physical abilities are no longer uniquely human.
Reskilling for Resilience: Focusing on Durable Skills
In light of these changes, a new focus on “durable skills”—skills that are harder for AI to replicate—is essential for career resilience. During my six-year tenure as a trustee at Nesta, we examined the impact of AI and robotics on workforce skills across sectors. Interestingly, Nesta’s Future of Skills (2017) report suggested that creative roles would be safe from automation. At the time, tasks requiring originality and artistic judgement seemed challenging for AI. However, generative AI has changed this landscape. Tools like DALL-E, Suno, Sora, and Midjourney can now create photorealistic images, artwork, videos, and even compose music, putting creative roles within AI’s reach.
Here are several core skills likely to withstand automation:
Critical Thinking and Problem-Solving: Skills involving complex judgement and adaptability in ambiguous situations.
Emotional Intelligence and Human-Centred Design: AI lacks the nuanced empathy required for effective human interaction.
Creative Strategy and Innovation: While AI can assist in creative processes, strategic thinking and originality remain human strengths.
Complex Communication and Negotiation: Roles requiring persuasion, influence, and relationship management resist automation due to deep interpersonal requirements.
Building adaptability and lifelong learning habits will be essential.
The Role of Organisations: Creating a Culture of Continuous Learning
For employers, adapting to this rapid change is equally crucial. Organisations need to develop or access agile training programmes that focus on reskilling and upskilling to align with evolving technological needs. Cultivating a learning culture that values curiosity and continuous improvement will help ensure a workforce that remains competitive.
Leveraging AI-driven learning platforms, microlearning, and digital tools makes learning accessible and tailored to individual needs. When employees feel empowered to grow, they’re more likely to stay engaged and add value to their roles.
The Role of Government: Preparing the Workforce for the Future
With the half-life of skills shrinking and technology increasingly displacing both cognitive and physical roles, government support is critical for preparing society for a new economy. Education reform is essential, particularly in how curricula are structured to emphasise durable skills like critical thinking, problem-solving, and emotional intelligence. The World Economic Forum stresses that education must align closely with future labour market needs to prepare the workforce for valuable skills 10–20 years from now.
Governments should also support lifelong learning through funding and incentivising training initiatives to facilitate reskilling. Singapore’s SkillsFuture program provides citizens with credits and access to government-funded training programs, helping workers adapt to new technologies and meet evolving industry demands.
Collaborating with businesses to develop public-private partnerships can also help ensure training programs are aligned with real-world needs, readying the workforce for emerging roles in an AI-driven economy.

Adapting with Resilience: Embracing Change and Anticipating the Future
The accelerating half-life of skills presents both a challenge and an opportunity. Individuals who develop durable skills and commit to continuous learning will have a significant advantage. However, we must also confront the reality that not everyone will transition easily into roles requiring complex human-centric skills.
As technology advances, we face a new set of questions around work, economics, and society. In the longer term, the implications of AI and automation will demand that we rethink economic structures, taxation, and income distribution, as well as how we define “work” in a society where work as we know it is no longer necessary.
While individuals can take steps to enhance their resilience, policymakers must prioritise educational reform and expand access to relevant training. Assuming our future will mirror the recent past is a mistake. We must develop a workforce prepared for a world where we’re not the fastest, smartest, or most capable.
Eventually, the half-life of skills may be measured in days or weeks—not years.
What do you estimate your skills half-life to be?
