Master of None.
Why the age of the specialist has blinded us to the builders who work across the seams — and why sovereignty needs them.
The proverb was mutilated on its way to us. "A jack of all trades is a master of none" — that is where most people stop, and they stop there because it is convenient. The full line runs on: "but oftentimes better than a master of one." The world kept the insult and quietly discarded the wisdom, and in doing so it told on itself.
We live inside a cult of specialisation. It is so total that we mistake it for the natural order, but it is a recent invention — a product of the industrial age and the institutions it built. Specialisation optimises for legibility. It produces expertise that fits on a single line, careers an organisation can slot together like parts, knowledge that can be certified and therefore trusted. It has given us extraordinary depth. It has also given us a peculiar blindness.
Because the problems that matter most do not respect the boundaries we have drawn around our disciplines. Consider what it actually takes to move money between two African markets. It is a financial problem — licences, settlement, currency. It is a technological problem — the systems that clear and record the value. It is a regulatory problem — the rules, and the rooms where they are written. It is a problem of trust — whether a counterparty, a bank, a market believes the whole thing will hold. And beneath all of it, it is a problem of narrative — the story a continent tells about whether it can build such things at all.
No specialist owns that problem. Each owns a piece of it. The value — and the failure — lives in the seams between the pieces, and no one is trained to work the seams. That is the territory the specialist cannot see, because seeing it requires having gone deep on both sides of a boundary and then standing in the gap between them.
Translation, at scale, is its own mastery — a mastery no one issues a certificate for.
This is what the caricature of the generalist gets wrong. The generalist is imagined as someone who knows a little about a great many things — shallow everywhere, useful nowhere. But the builder the proverb actually describes is something else: someone who has gone deep enough in several domains to translate between them. It is simply a mastery no one issues a certificate for, which is why we have learned not to value it.
I have built a payments company and made films. I have worked in identity and in security, and I have backed infrastructure at the level of systems and settlement. Read from the outside, that looks like restlessness — a man who could not decide. It was never that. Each of those was deep enough to teach me something none of the others could, and the only reason the work I do now is possible is that I can hold them together: I know that a financial rail is also a trust problem, that trust is also a matter of narrative, that narrative is also, increasingly, a technology. The domains are not a list of hobbies. They are the instruments required to build one thing.
The age of the specialist will not end, nor should it; some problems demand a lifetime spent going down. But we have allowed depth to become the only kind of seriousness we recognise, and we have quietly stopped valuing the people who can hold the whole. The largest questions in front of us — whether a continent gets to determine the terms of its own future — will not be answered by deeper specialists working further down their separate shafts. They will be answered by builders willing to be master of none, and better for it.
