The interview centered on Baillie Gifford partner Tom Slater and his paper [AI Isn't Coming for Your Job. It's Coming for Your Mind](https://www.bailliegifford.com/en/uk/individual-investors/insights/ic-article/2026-q1-ai-isn-t-coming-for-your-job-it-s-coming-for-your-mind-10061431/). For job seekers and employers, the framing matters because the headline numbers on AI displacement keep missing the slower, more dangerous shift: a workforce that looks more productive while losing the judgment that makes productivity compound. [Metaintro](https://www.metaintro.com) tracks both sides of that story. ## What Does Cognitive Offloading Actually Mean for Workers? Cognitive offloading is the act of pushing a mental task onto an external tool, and humans have done versions of it for centuries with notebooks, calculators, and search engines. What changes with generative AI is that the offloading covers reasoning itself, not just storage or retrieval. A 2025 review in MDPI's Societies journal traced [the rise of cognitive offloading in AI-mediated work](https://www.mdpi.com/2075-4698/15/1/6) and found a consistent negative correlation between heavy AI use and measured critical thinking, with the relationship strongest among younger workers who learned the task with AI from day one. The mechanism is not that AI makes people dumb. It is that AI makes the effortful parts of thinking optional, and effort is what builds the underlying skill. Reading a draft contract is faster than writing one. Editing a generated forecast is easier than building the model. Each shortcut feels rational in the moment. Over months, the practice that produced the senior judgment shareholders and clients pay for never happens. Cognitive scientists draw a sharp line between offloading memory, which has always made workers more productive, and offloading judgment, which is the new and untested category. Memory offload frees attention for higher-order reasoning. Judgment offload removes the reasoning step itself, so the worker becomes an editor of a system they cannot fully audit. That distinction is what makes the current wave different from spreadsheets, search, or even early machine learning tools, and it is why the same researchers who built these systems are now urging companies to track skill maintenance the way they track productivity. ## What Does the Research Actually Show? Two studies anchor the current debate. In February 2025, researchers at Microsoft Research and Carnegie Mellon University published [The Impact of Generative AI on Critical Thinking](https://www.microsoft.com/en-us/research/publication/the-impact-of-generative-ai-on-critical-thinking-self-reported-reductions-in-cognitive-effort-and-confidence-effects-from-a-survey-of-knowledge-workers/), a survey of 319 knowledge workers describing 936 real workplace uses of generative AI. Across the cognitive tasks the study tracked, the share of examples where workers reported "much less" or "less" effort hit 72 percent in knowledge work, 79 percent in comprehension, 76 percent in synthesis, and 55 percent in evaluation. Higher confidence in the AI tool correlated with less critical thinking. Higher confidence in one's own ability correlated with more. The MIT Media Lab study [Your Brain on ChatGPT](https://www.media.mit.edu/publications/your-brain-on-chatgpt/) added a neural layer. Researchers split 54 participants into a ChatGPT group, a search engine group, and a brain-only group, then used EEG to map brain connectivity during essay writing across multiple sessions. The brain-only group showed the strongest and most distributed networks. The search group came in the middle. The ChatGPT group showed the weakest connectivity, and when forced to write without the tool in a later session, they performed worse than the group that had never used it. The authors named the pattern cognitive debt, and as [Fortune covered](https://fortune.com/2025/02/11/ai-impact-brain-critical-thinking-microsoft-study/), the worry is that workforce judgment ends up atrophied and unprepared when the exceptions arrive. Critics have noted that both studies are early and that self-reported cognitive effort is a soft measure, but the convergence with the EEG findings is hard to dismiss. The Microsoft and Carnegie Mellon paper also found that workers who reported high confidence in the AI's output engaged the least critical effort, which is the opposite of the verification behavior most enterprise AI policies assume. A separate working paper from the National Bureau of Economic Research, examining call center agents using generative assistants, found that newer hires gained the most short-term productivity but showed the least skill growth over six months, reinforcing the pattern that the easier the tool makes the work, the smaller the developmental footprint left behind. ## How Is This Reshaping the Skill Pipeline at Work? The strongest workplace evidence sits at the entry level, where the pipeline of routine work that used to train juniors is collapsing fastest. According to Revelio Labs data cited in [CNBC's coverage of young workers and AI](https://www.cnbc.com/2025/11/20/why-ai-may-kill-career-advancement-for-many-young-workers.html), entry-level job postings in the United States dropped 35 percent from January 2023 to June 2025. A Stanford Digital Economy Lab study tracked by [Axios](https://www.axios.com/2025/08/26/ai-entry-level-jobs) found employment for software developers aged 22 to 25 fell nearly 20 percent from its late-2022 peak. A joint MIT, Northwestern, and Yale paper found that when AI can handle most of a role's tasks, headcount in that role at the company drops about 14 percent. Starting wages tell a parallel story. The same research line found that pay in AI-exposed companies fell 4.5 percent after the launch of ChatGPT, led by a 6.3 percent drop for junior positions. The Conversation framed this as the looming [end of young people learning on the job](https://theconversation.com/ai-could-mark-the-end-of-young-people-learning-on-the-job-with-terrible-results-275352). The grunt work that taught new analysts how to read a deal, new associates how to find a precedent, and new engineers how to debug their way out of a corner is the same grunt work generative tools handle in seconds. The pipeline problem is structural, not cyclical. Junior roles historically served two functions, doing volume work the firm needed done and serving as the apprenticeship that produced the next layer of senior talent. AI handles the volume work cheaply enough that the apprenticeship loop is being quietly removed from the org chart. Hiring managers say the math is straightforward in the short term, but partners and operations leaders are starting to ask where the firm's next cohort of capable mid-level workers will come from in three years. The same erosion is visible in finance, where rotational programs are being cut, and in consulting, where staffing models that once mixed AI-free analysis with mentored coaching are tilting toward AI-first pipelines. ## Why Does the Quiet Erosion Worry Investors and Employers? Tom Slater's argument is unusual because it comes from a long-horizon equity investor rather than a futurist. His view, summarized across [Trustnet's coverage of the Scottish Mortgage piece](https://www.trustnet.com/fundswire/13471797/ai-isnt-coming-for-your-job-its-coming-for-your-mind), is that AI reliably improves immediate task performance while degrading the human capabilities that produce that performance, which leaves a company with better results today and weaker people tomorrow. He pegs generative AI as automating roughly 30 to 40 percent of an employee's workload, leaving fewer entry-level roles and fewer ways to train the seniors a company will need in five years. Wharton's faculty have raised a related flag. Research summarized through [Wharton's AI and the Future of Work Conference 2026](https://ai.wharton.upenn.edu/ai-and-the-future-of-work-conference-2026/) describes an efficiency trap where productivity gains become a perpetual treadmill, and a measurable drop in personal agency tracks rising trust in AI systems. Workers report feeling less capable of independent judgment even in domains where they used to be experts. For employers, the bill comes due in the form of senior pipelines that thin out years before anyone notices. We covered the same pattern from the management angle in [our piece on critical skills your team is losing](https://www.metaintro.com/blog/ai-deskilling-critical-skills-your-team-is-losing-2026). The investor concern lands harder because it lines up with what chief financial officers are already seeing in cost structures. Companies that pushed aggressive AI adoption in 2024 and 2025 are reporting flat or rising error rates in customer-facing work, with the bulk of incidents traced to junior staff approving outputs they did not have the skill to evaluate. None of that shows up in a quarterly earnings call, but it shapes the long-horizon equity case Slater is making. ## What Is Happening Inside Schools and Universities? The classroom mirrors the office. The [Stanford 2025 AI Index education chapter](https://hai.stanford.edu/ai-index/2025-ai-index-report/education) reports that roughly four in five US high school and college students now use generative AI for school work, primarily for research, editing, and brainstorming. Only half of middle and high schools have an AI policy and just 6 percent of teachers describe those policies as clear. An [arXiv working paper on AI tools and learning outcomes](https://arxiv.org/html/2510.16019v1) found that students using AI for problem sets performed better on those assignments and worse on later assessments that blocked the tool, a pattern that maps cleanly onto the MIT lab result. The pipeline effect on work is straightforward. Tomorrow's junior analysts, engineers, and editors are graduating from classrooms where they learned the task with AI in the loop. If the workplace has also stripped out the routine reps that build the underlying skill, there is no remaining place in the system where mastery is forged. Universities have started to respond, but unevenly. A handful of business schools have introduced AI-free assessment tracks where students must produce work product without any generative assistance for designated milestones. Engineering programs are debating whether timed, in-person problem sets should return as a counterweight to take-home work where AI use is impossible to police. Career services teams meanwhile report that students are increasingly anxious about a market where the entry-level rung is shrinking, and where employers say they want judgment but hire on output speed. The next two graduating classes will be the first to enter knowledge work with AI as a default, and the early data on how they perform once the training wheels come off will shape hiring patterns for the rest of the decade. ## What Should Employers Actually Do About It? The serious answers do not look like an AI ban. They look like deliberate skill protection. A growing playbook is emerging across HR research, and three pieces show up in almost every credible version of it. First, mandate AI-free reps for specific high-stakes skills. That can be junior associates writing their first ten client memos without the tool, analysts running their first quarter of models by hand, or engineers debugging without the autocomplete. The point is not nostalgia. It is to preserve the practice loop that produces senior judgment. Microsoft's own researchers used the [phrasing atrophied and unprepared](https://www.404media.co/microsoft-study-finds-ai-makes-human-cognition-atrophied-and-unprepared-3/) for what happens when the loop disappears. Second, redesign entry roles so they include genuine reasoning work, not just AI-output review. The IESE Business School analysis of [AI's impact on junior wages](https://www.iese.edu/insight/articles/artificial-intelligence-junior-employees-wages/) makes the case bluntly: companies that protect early-career reasoning roles preserve their senior pipelines, while companies that gut them save money now and pay for a leadership gap in five years. Third, measure judgment, not just throughput. Promotion criteria that reward velocity push everyone toward maximum offloading. Criteria that reward exception handling, novel-case reasoning, and unaided problem solving create the incentives that protect the skill. ## What Should Workers Do, Practically? The framing that has resonated most with readers we have spoken to is simple. Use AI for tasks where the goal is the output. Do the work yourself when the goal is the skill. Drafting a routine email where you already know how is fine. Writing your first five board memos, your first five model walk-throughs, or your first five customer escalations is where the skill is built, and offloading those is the move that costs years of capability later. It also helps to keep a private no-AI file. Once a week, write something hard without the tool. Solve a problem in your domain end to end. The MIT EEG result suggests that even after months of heavy reliance, the underlying networks can be reactivated, but the activation has to be deliberate. We wrote more about that practice in our coverage of [the AI comfort trap](https://www.metaintro.com/blog/ai-comfort-trap-automation-eroding-skills-hireable-2026). It is also worth being honest about the labor market context. Refusing to use AI is not a viable career strategy for most knowledge workers in 2026, and signaling that refusal in interviews is more likely to close doors than open them. The realistic stance is fluent and deliberate, meaning you can use the tool at the level your employer expects while protecting the underlying skill that makes your judgment worth paying for. Workers who can both move fast with AI and demonstrate, on demand, that they understand the reasoning behind the output are the ones likely to keep moving up the ladder as the entry rungs reshape underneath them. ## People Also Asked **Is AI actually making workers less intelligent?** The research does not say AI lowers intelligence. It says AI reduces the effort spent on the cognitive tasks that build and maintain skill, and the loss shows up in unaided performance over time. The MIT study and the Microsoft and Carnegie Mellon study both point to this gap between in-tool performance and out-of-tool capability. **Which jobs are most exposed to the cognitive offload effect?** Knowledge work where reasoning, judgment, and synthesis are the core product, including law, finance, consulting, software, and journalism. Roles where AI can do 30 to 40 percent of the workload sit in the danger zone for the training pipeline. **Are entry-level workers really losing the most?** Yes. Entry-level postings are down 35 percent since 2023, junior wages in AI-exposed firms are off 6.3 percent, and software-developer employment for ages 22 to 25 has dropped nearly 20 percent from its 2022 peak. The work that used to train those workers is the work AI is best at.
