    The Principle of Least Intelligence: How Much AI Does the Work Need?

    In September 2026 a start-up called TypeSafe AI shipped a model that does not write text at all: it takes a fixed set of options and returns a probability for each, and software acts on the answer. In October Microsoft followed with a model of the same kind, saying it is increasingly important to choose the right model for the right job. The question neither supplier can answer is whether an organisation has a method for the choosing. In this episode of The Board in the Machine, Mario Thomas — Chartered Director and Fellow of the Institute of Directors — sets out the Principle of Least Intelligence: apply no more intelligence than the outcome needs, where least means sufficient, not weakest. He explains why the answer is rarely one model but a mix of capabilities, each doing the job it is good at, and why the cost that matters is the whole system's, including what it takes to run and to check. For a Board, that moves from choosing a model to stewarding a portfolio of capabilities. Mario works through the older rules the principle takes its inspiration from, security's principle of least privilege and the web's rule of least power, and a 2025 NVIDIA paper arguing that small language models are enough for much of what agents do. He separates the two decisions behind any AI system: how much capability the work gets, and how much the system is allowed to do without a person checking. He also asks how a decision with no written reasoning can be explained, and why the explanation belongs to the system around the model. The payoff is five questions a Board can ask of any AI system without knowing anything about the model inside it. This episode is for directors, chairs, and executives whose organisations use one frontier model for every task, and who want a method for matching capability to need as the industry moves towards smaller, narrower models.

    Managers Own the Workflow: Where the AI Business Case Becomes Real

    A Gartner analysis from December 2025 found AI saves about five hours per person per week. The manager may see nothing like that, because the team spends part of the saving checking what the AI produces, coordinating work between people and agents, and dealing with the exceptions the agents hand back. Each agent deployed adds a supervisory duty to the manager's job, and the job description rarely says so. In this episode of The Board in the Machine, Mario Thomas — Chartered Director and Fellow of the Institute of Directors — examines where the AI business case becomes real: in the manager's job. In organisations deploying AI, managers responsible for the people in their teams are now responsible for fleets of software agents, checking what the agents produce and deciding what to do with the time they free. The business case that put the agents there says nothing about how that change is to be managed, and the Board is rarely asked to decide it. Mario works through the evidence: Harvard Business Review's June 2026 research on middle managers validating AI output with no formal support, Gallup's finding that manager engagement fell from 31% to 22% in three years, McKinsey's work on the rise of the agent manager, The Conference Board's 2026 training survey, the Stanford Digital Economy Lab's reported pattern in young workers' employment, and a 1983 paper on the ironies of automation. The takeaway: five questions a Board can put to the executive, from whether the AI plan redesigns the manager role to how the next managers will be grown when the work they would have learned on has gone to the agents. This episode is for directors, chairs, and nomination committee members in organisations approving AI business cases built on time savings, who want to know whether the job those savings depend on has been designed or has absorbed the change by default.

    The Supplier Grades the Customer: What Pacing the Frontier Means for the Organisations That Buy It

    Access to the most capable models is already decided by the supplier's assessment of the customer. The suppliers' own published pages describe tiers: the organisations a supplier has vetted or found eligible, the organisations that may apply and be approved, and everyone else on standard terms. Today an organisation outside one supplier's tier can go to another, but if the frontier laboratories agree common standards, as Anthropic's chief executive has proposed, the tier would follow the customer. In this episode of The Board in the Machine, Mario Thomas — Chartered Director and Fellow of the Institute of Directors — examines what a proposal to slow the rate at which frontier models improve would mean for the organisations that buy them. The episode covers what pacing asks for, why a release checkpoint would make certificates the thing that matters, and why three decisions a Board answers for, what it can use, on what terms, and how quickly that capability improves, are being made at tables the Board does not sit at. Mario works through Dario Amodei's essay arguing that the laboratories must pace the frontier, the agreement of OpenAI's chief executive and Elon Musk's three-word reply, Anthropic's published pages on Fable and Mythos 5.1 and on its enterprise frontier safeguards, OpenAI's documentation for trusted access to its most capable cyber model, and his own earlier work on the AI Sovereignty Trilemma and the Reasoning Gap. The takeaway is three questions that belong on the risk register beside model availability, with a named owner: whether the Board accepts that a competitor may reach frontier capability first and that the supplier decides the order, how the organisation stays competitive for as long as that lasts, and what running open-weight models instead would cost in capability, certification, and money. This episode is for directors, chairs, and executives whose products, workflows, and operating plans already depend on models reached through a contract and an API, and who would rather choose their position than learn it from a competitor.

    Nothing Has to Leave the Building: The AI Risk That Is Not a Data Breach

    No system has been breached, no contract has been broken, and no employee has resigned, yet an organisation's know-how may be leaving through the tools its best people use every day. A risk shaped like that sits beside the security, legal, and human resources desks without falling inside any of them, and it reaches the Board only if the Board asks for it. In this episode of The Board in the Machine, Mario Thomas — Chartered Director and Fellow of the Institute of Directors — sets out why this is a transfer of capability rather than a breach of data, and why the decision a Board can govern comes earlier than any assurance from a supplier: which work goes into these tools in the first place. Mario examines The Information's report of 14 September, which says Nvidia, Palantir, and Booz Allen Hamilton are among the organisations restricting which work goes to the most capable frontier models, and the exchange that followed OpenAI's announcement of a proof for one of the Millennium Prize problems in mathematics, where a mathematician who had put his project drafts into a coding tool asked whether they had been used in training, and OpenAI said afterwards that his prompts could not have influenced the system, an answer the episode takes at face value. He also works through Palantir's July paper on AI sovereignty, from a company that sells access to these models through its own software and so has an interest in the argument. Listeners come away with three questions a Board can ask at its next meeting, and a named owner to bring the answers back. This episode is for chairs, directors, and executives whose organisations have approved the use of a frontier model without deciding which work should go to it, and who would rather set that rule now than leave the line to whoever happens to be at the keyboard.

    The Debugging Gap: The Skill Your AI Business Case Assumes You Still Have

    In one recent experiment, reported in a preprint, novice programmers who had built working software with unrestricted AI assistance were given a short maintenance task without the tool. Of those, 77% failed it, against 39% of a group whose AI use had been designed to keep them reasoning. Building working software and being able to fix it are different capabilities. In this episode of The Board in the Machine, Mario Thomas — Chartered Director and Fellow of the Institute of Directors — defines the Debugging Gap: the widening distance between how much AI-generated code needs checking and repairing, and how many people can do that work. He explains why it belongs to Boards and not to engineering management. Mario works through the evidence and its limits. Anthropic's randomised controlled trial found that developers learning a new library with AI scored 17% lower on comprehension, with the largest gap on the debugging questions. Stanford's Digital Economy Lab finds employment among workers aged 22 to 25 in the occupations most exposed to AI about 19% below where it would be had it kept pace with less-exposed peers, mainly through reduced hiring. Faros AI, a vendor in this market, reports teams with high AI adoption merging 98% more pull requests while review time rose 91%. None of this proves that engineering capability is in decline, and Mario says so. What the trials do show is that outcomes turned on how the tools were used, not on whether they were available, and he sets out three questions a Board can put to its technology leaders. This episode is for directors, chairs, and the Boards approving AI coding tools on a business case that counts the hours saved. When a Board approves that investment it also approves a position on how its developers build skill, whether or not the paper in front of it says so. Read the full article at mariothomas.com

    The Deadline Moved: What the EU AI Act Deferral Reveals About Boards

    On 2 August 2026, the EU AI Act's rules for standalone high-risk systems were supposed to take effect. They will not. Six days before the deadline, the EU brought an amendment into force deferring those obligations to December 2027, because the standards and implementation machinery needed to make them workable were not ready. In this episode of The Board in the Machine, Mario Thomas, Chartered Director and Fellow of the Institute of Directors, examines what the deferral reveals about any Board whose AI governance was built around a regulatory date. A governance programme that exists because a deadline was coming is a compliance project, and when the date moved, the discipline moved with it. The instability is global: a proposed standards body in the United States covers only the frontier laboratories, the United Kingdom has asked existing regulators to govern at the point of use, and China regulates piece by piece while drafting a comprehensive law. No regime on offer covers everything a Board might deploy. Mario sets out what never moved: the directors' duties that predate the AI Act, the obligations that still apply from 2 August, and Minimum Lovable Governance as the anchor that holds under any regulatory timetable. He closes with three questions for the next Board agenda: which deployments would count as high-risk, where the organisation's ethical bar sits and who set it, and which obligations remain live regardless of the deferral. This episode is for directors, chief executives, and Boards who deploy AI systems today under law that applies today. Accountability is a condition of deployment, not a product of regulation.

    The Balancing Item: The AI Oversight Cost Your Business Case Never Priced

    Every AI business case counts the hours saved. Almost none counts the hours added: the reviewing, correcting, and supervising that AI outputs demand before anyone can rely on them. That labour is real, and in most organisations it is absorbed silently by people on top of their existing roles. In this episode of The Board in the Machine, Mario Thomas, Chartered Director and Fellow of the Institute of Directors, examines the cost the True Investment Profile predicted and Boards have not priced. Research published in March 2026, surveying nearly one and a half thousand full-time workers at large American companies, gives the consequence a name: a distinct mental fatigue that attaches to heavy AI oversight loads, while workers using AI only to replace routine tasks report less burnout, not more. The burden is a work-design outcome, and work design is something Boards can govern. Mario sets out the governance response. Price the oversight in every business case. Design review into roles rather than on top of them. Set span-of-control expectations for human and AI working. Balance the portfolio between burnout-reducing replacement and fatigue-generating augmentation left unresourced. Watch the leading indicators of a control under strain: review backlogs, rubber-stamping rates, error escapes, and attrition in oversight-heavy roles. This episode is for directors, chief executives, and the Boards who attest to effective human oversight while the humans providing it are at cognitive capacity. The closing question is the one that matters: which of those attestations would survive an honest capacity audit? Read the full article at mariothomas.com

    Governing the Redeployment Dividend: Turning Saved Hours Into Value

    Teams that deploy AI save the equivalent of five hours per person per week, and most of that time is then spent on non-value-added tasks. The saving is real. What happens to it next is the problem, and it is a problem that belongs to the Board. In this episode of The Board in the Machine, Mario Thomas, Chartered Director and Fellow of the Institute of Directors, returns to the Redeployment Dividend, the argument that AI's real prize is releasing intellectual capital from undifferentiated work rather than cutting headcount. The evidence now shows what happens when that dividend is left ungoverned. Surveys across HR and sales find freed hours reabsorbed by the low-value work that was already there, and a study of nearly six thousand executives across four countries finds that while most firms now use AI, roughly nine in ten report no measurable impact on productivity at their own firm. The explanation is an accountability gap. AI owns the execution of the work. Managers own the workflow it sits within. But in most organisations, nobody owns whether the freed capacity creates value. Mario sets out a single governance discipline to close that gap: change the success metric from headcount to redirection, give redeployment an owner, redesign the work to receive the recovered hours, measure the downstream outcomes rather than the time saved, and govern what the organisation deliberately stops doing. This episode is for directors, chief executives, and the Boards who can already quote the hours their AI tools recover but cannot yet say where those hours went. Time saved is an input, never the outcome. Read the full article at mariothomas.com
