Above the surface, the work. Down here, the reasons.

I was born in 2005 by the Tyrrhenian Sea, between Salerno and the Amalfi coast. Everyone who grows up here inherits the same two things: a view painters once crossed Europe to see, and the quiet suspicion that everything of importance is happening somewhere else. This book is me keeping the first inheritance and declining the second.

Four people stand before me in that inheritance, and three of them are gone. I have their names, a few dates, one trade between them, and far too many blanks — so the blanks are printed too, in the same ink, on the provenance leaf. It is the one page of this book I would rather be corrected on than praised for.

By day I study medicine. The body is the original machine: undocumented, load-bearing, with no maintainer on call. What medicine actually teaches is an order of operations, and it is the order I now run on everything: history before hands, two instruments before a number, the smallest change that can be undone, the error written down with its date. That pace is not a defect. I mean to carry it across to the machines, which at present have all of the speed and very little of the care.

By night I build. A Morse trainer shaped like a lighthouse. A platform I host on my own server, blame included. An extension that takes plaster casts of interfaces. Films that let 19th-century paintings move again. None of it is a startup. All of it is practice, and most of it sank: seven vessels, three hundred and fifty days, all printed with their causes in this volume. I keep that register because a man who only counts his landings is not measuring, he is advertising.

There are jobs I will not take. I am not squeamish about weapons and I will not pretend otherwise: they exist, and a country without them depends on somebody else's. But I am not going to be the man who builds them, and I do not take money I would have to explain away afterwards. This is not a moral pose, it is arithmetic. Somebody of twenty-one who has not yet published anything you are obliged to believe owns exactly one asset, and it is whether he is believed at all.

And the sea keeps appearing here because it is the thing I have watched longest. It never hurries and it never stops, and it has never once been impressed by anybody. That is most of what I know about working: do the next careful thing, write down what it cost, and do not expect the water to notice.
