In the evolving landscape of artificial intelligence, it's easy to assume that AI only affects repetitive, mundane work. After all, you can’t automate expertise. Or can you? This assumption overlooks the profound effects of Generative AI (GenAI) on a significant segment of the workforce: knowledge workers.
Knowledge workers are professionals with deep expertise in their domain, gained through years of experience over their career, and most often in careers that follow post-secondary education.
Historically, knowledge worker roles were seen as less susceptible to automation due to the expertise and human judgment required to perform cognitive tasks. However, with the emergence of GenAI, this view is changing rapidly. GenAI can now analyze vast amounts of data, generate insights, and perform complex tasks that once required years of human experience and education.
The widespread integration of GenAI into work challenges the long-held notion of how knowledge workers are developed:
Education + Experience = Expertise.
GenAI doesn’t replace expertise - it supercharges it by amplifying the value of human judgment, contextual awareness, and experience from years of navigating complex situations. While GenAI may not necessarily replace knowledge worker jobs, those who learn to work with GenAI will be better prepared for knowledge work of the future.
This new paradigm offers both challenges and opportunities as knowledge workers adapt to a new reality where AI plays a central role in their professional lives.
In the past, technological advancements often led to the displacement of workers, more commonly for roles requiring lower levels of education and skill. However, GenAI’s integration is different because it affects the day-to-day work for highly educated and skilled workers, too.
Knowledge workers — such as software developers, financial advisors, teachers, architects, lawyers, doctors, and marketing professionals — are witnessing an evolution of their roles with GenAI.
Statistics Canada1 found that GenAI disruption is strongly correlated with education level attainment. Highly educated workers tend to be in knowledge-intensive roles—exactly the kinds of jobs where GenAI excels. GenAI models learn just like humans do, except they can access and absorb much more information at a significantly faster rate. Canada leads G7 countries2 with the highest working age population with post-secondary education. Nonetheless, we’ve seen that education alone won’t be enough to stay resilient.
This raises questions about the future role and value of traditional education. If GenAI can rapidly replicate and surpass many technical skills that higher education once provided, what kind of education truly prepares someone to thrive in an AI-augmented economy? Aspiring professionals will need critical thinking, ethical reasoning, and adaptability to work alongside AI, and when necessary, challenge AI-generated insights.
To protect Canada’s labour market and economy from significant workforce displacement, we must redefine both education, apprenticeship models, and continuous learning for an AI-enabled world.
The future of expertise does not lie solely in acquiring knowledge — it lies in the ability to translate, contextualize, and challenge knowledge in real-world situations, where human experience makes all the difference.
Experience, often gained through apprenticeship and tenure within organizations, has long been the cornerstone for developing the strategic, problem-solving skills and judgment needed in complex cognitive knowledge work. This hands-on learning was not just a pathway to mastery, but also a mechanism for preserving organizational knowledge itself. Consider the common reality of "years of experience" as a requirement on a job posting, which assumes that valuable knowledge and skills are accumulated through prolonged exposure and practice within a field.
However, our work with clients across different industries reveals a disruption to the apprenticeship model. GenAI is not just altering tasks. It’s rewriting the traditional equation — education + experience = expertise — and commoditizing knowledge. When AI can instantly generate insights, draft documents, write code, or even produce creative strategies, the competitive advantage no longer lies in what you know. Instead, it lies in how effectively you can interrogate, contextualize, apply, and execute what the machine knows, while considering your organization’s complexities.
This shift is particularly pronounced in professional services, where the entire business model has historically relied on the leverage pyramid: junior employees performing foundational work, gradually building knowledge and judgment, while senior professionals focus on higher-value strategy and client relationships. GenAI disrupts this model at both ends — automating foundational work while augmenting senior-level decision-making. The result? Junior employees risk losing critical developmental experiences, and firms must rethink how they cultivate future leaders when “learning by doing” no longer follows a predictable path.
Using our proprietary workforce analysis tool, Periscope, we analyzed how GenAI reshapes day-to-day tasks in four knowledge worker career paths. Swipe through the carousel to explore how specific tasks at junior and senior levels are evolving across professions.
In the legal profession, GenAI can now handle much of the legal research and document reviews that junior lawyers typically perform. This accelerates delivery, but also compresses the traditional apprenticeship process, requiring junior lawyers to engage in higher-order thinking far earlier in their careers. Similarly, in software development, AI-assisted coding and debugging mean that junior developers must quickly pivot from learning syntax to mastering systems thinking and architectural problem-solving.
The traditional career ladder was built for a world where knowledge accumulation was linear, and experience was gained by gradually layering insight on top of experience. GenAI breaks that linear path. Organizations that fail to redesign their apprenticeship pathways risk losing not just their next generation of talent, but their competitive edge.
If education and experience are both being disrupted, how will we build the experts of tomorrow? This question sits at the heart of the future of work — and the future of entire industries.
The traditional pathway to expertise is evolving. While GenAI provides easy access to knowledge, it cannot replace human-only capabilities like judgment, creativity, empathy, deep understanding and critical thinking. Sustained success requires action from both organizations and individuals. Organizations must adapt their strategies to support our economy and ensure the continued growth of expert knowledge workers. Simultaneously, knowledge workers must demonstrate adaptability and curiosity as they integrate GenAI in their work.
Here are four key steps to ensure your organization continues to grow with the emergence of GenAI:
AI doesn’t erase the value of knowledge work; instead, it rewrites the rules of what it means to be an expert. With the right training, knowledge workers can augment their work with AI to unlock capacity for human-centric tasks, and create business value faster.
