Make it yours
AI can get you to the conclusion. It cannot get you to the conviction.
Issue #11 · August 8th 2026
I write about the things that don’t change in a world that won’t stop changing.
I believe adding real value is what gives us purpose, keeps us happy and improves our lives.
Everyone can now produce a thirty-slide presentation summarising complex information in minutes. The output looks professional. The data is accurate. The structure is sound.
And yet something is missing. The moment someone asks a hard question, the room feels it. The person presenting doesn’t own the material. They assembled it. That gap is immediately visible to anyone who has sat across the table from someone who actually does own it.
Life is selling
Every professional interaction is a sale. To investors. To customers. To partners. To your own product team. To a coworker you need to bring along on a decision. The context changes but the dynamic doesn’t.
Selling is not about persuasion techniques or slide design. It is about giving another person the confidence that you can deliver what you are promising. That confidence is not transmitted through a deck. It is transmitted through the felt sense that the person in front of you has the topic completely under control. That if you pulled the slides away and asked a hard question at 11pm in a due diligence call, they would not reach for anything. They would just answer.
That feeling is either there or it isn’t. And it is very easy to catch when it isn’t.
“Selling is giving another person the confidence that you can deliver what you are promising. That confidence is not transmitted through a deck.”
What AI actually compresses
AI is genuinely good at managing large volumes of information and producing accurate conclusions. If you point it at the right questions, focus it on the real problem, and apply enough judgment to the output, it compresses the time from raw data to structured insight dramatically. A financial model that would have taken a week can be stress-tested and refined in an afternoon. A market analysis that required three analysts can be assembled by one person with the right tools.
What it does not compress is the time required to internalise that insight. To run it against your own experience. To find the two assumptions that are slightly off and understand why. To be able to explain the whole thing from first principles when someone pushes back hard in a room full of people who are deciding whether to trust you with their money, their partnership, or their time.
That process happens at human speed. It always has. It still does.
The bottleneck is human
We are the bottleneck. Not because we are slow, but because real understanding, the kind that holds up under pressure, cannot be shortcut. It requires the material to pass through a person who has enough context and experience to know what it means beyond the surface.
A complex financial model built by AI that has not been internalised and contrasted against lived experience by the person presenting it will not survive serious scrutiny. An investor asking two probing questions will feel the absence immediately. The model might be perfect. The conviction is missing. And conviction is what closes.
The same applies to a technical solution, a go-to-market plan, a regulatory argument. The quality of the underlying work is necessary but not sufficient. The person who spearheads it needs to have made it theirs. Completely. To the point where they could rebuild it from scratch if the slides disappeared.
“The model might be perfect. The conviction is missing. And conviction is what closes.”
The skill that emerges
What this creates is a new premium on a specific capability: fast internalisation and message replication.
The ability to take AI-generated conclusions, run them through your own judgment quickly, identify what holds and what doesn’t, make the whole thing yours, and then sell it with the kind of passion and confidence that only comes from genuine ownership. That skill is not technical. It is cognitive and emotional. And it is becoming more valuable the more people use AI to do the first half without doing the second.
The people who will win in this environment are not the ones who produce the best AI-assisted output. They are the ones who internalise fastest and sell hardest. The output is the starting point. The conviction is the product.
The invariant
In any complex system where humans make the final decisions — investing, buying, signing, hiring — there is always a need for the person who spearheads. Who has the topic under control. Who can be put under stress and not crumble. Who answers from conviction rather than from a slide.
AI is helping us get to the conclusions faster. That is real and it matters. But the time spent making those conclusions ours is not optional. It is not a step you can skip because the model did the analysis. It is the difference between a presentation and a sale.
As long as the decision makers are human, another human needs to sell them the conviction to act. I don’t see that changing any time soon. We want to be in the driving seat, using AI as the assistant. Time will tell if I’m wrong.
