“Sea level” is actually different everywhere, but in Britain, it remains a function, plus or minus, of ODN: Ordnance Datum Newlyn. This is the level measured within the town’s tidal observatory, constructed on the South Pier in 1915. The observatory takes the form of a hollow tower in which several floats are suspended, connected to a recording device. An inlet pipe allows the tower’s well to fill and empty with the Atlantic tides. Between 1915 and 2015 the mean sea level at Newlyn increased by 1.83 mm/year—and by 3.8 mm/year between 1993 and 2014. Each change in sea level is reflected in an incremental adjustment to elevations across the land.
The last official benchmark was carved on a milestone located outside a pub in Loughton, Essex, in 1993, before satellite-based systems took over the datum (today, a GPS antenna sprouts from the top of the tide tower in Newlyn). The Ordnance Survey still maintains a record of over half a million benchmarks, although many more have disappeared. Hiking clubs lead expeditions to find them, and hobbyist benchmarkers check them off their lists. When you start looking for them, you see them everywhere.
“Benchmarking” remains in use today as a term for establishing a baseline against which other data can be measured and judged: software performance, product quality, profitability, growth; quality, time, cost. But it’s worth remembering its origins not as a tool for establishing hierarchies, but for leveling; for connecting, rather than separating; and for understanding the whole earth, and everything that happens upon it, as a continuous, indivisible field, stretched across cities, forests, and mountains, and ever susceptible to the rhythm of the tides.

I actually studied AI at university, twenty years ago: exactly the wrong time, it turned out, to be studying it. The history of AI is one of booms and busts: “AI winters,” they were called, when the field seemed to sputter out after a series of advancements, and twenty years ago it was decidedly chilly. We learned about expert systems and neural networks from aging professors, but all the sensible students were learning about classical logic and statistics as preparation for careers in digital finance. It was another decade before the field would regain its energy, and—this is a controversial take—it would have little to do with conceptual breakthroughs. Rather, the growth of the internet, with its accompanying boom in processing capacity and data storage, would allow those same ideas—primarily neural networks—to be supercharged by graphics cards, digitized text and artworks, surveillance and social media, and the wholesale transference of everyday life to the online world. The AI “revolution,” if that’s what it is, is not a technological breakthrough, but the overwhelming accumulation of power and data in the hands of a few companies: power and data which rightfully belong to, and have been stolen from, everyone. But I digress.
I’d been noodling with this idea for some time: What if we used AI for something actually useful? It feels like we’re applying this new tool to all the wrong things: beating us at the games we enjoy, supercharging predatory capitalism, extracting and burning fossil fuels, depleting the planet’s resources, conflating images with art, encouraging extremism, suppressing rights, hallucinating, and so on and so forth. Wouldn’t it be infinitely more interesting if AI helped us do useful things in new and better ways, ways which we could not have imagined alone? Intelligences which we engaged with more like colleagues and collaborators than slaves and masters.

The anarchist anthropologist David Graeber, may he rest in peace, had a good bit on authority. He said that anarchists don’t oppose authority per se, but they study and critique it, and appraise its legitimacy. What he liked, he said, was self-subverting authority, authority which undermines its own basis. He gave the example of a teacher: A teacher knows something useful to their student, and so they have a natural authority; but if they do their job well, at the end of the process the student knows what the teacher knows, and their authority is spent. The hierarchy is flattened, and no further unequal power can accrue. The student is changed, and so is the world.
Of course it’s possible to learn things from AI, but, for me, real intelligence resides not in an ability to extract and dominate, but in the capacity to share, co-exist, and thrive together. There are many ways of being intelligent, as many as there are living beings, each one unique and valuable. The real challenge of AI is not in building ever more powerful systems—this is difficult, but inevitable—the challenge is to find what relationships between different intelligences benefit us all. The challenge is to choose the kind of world we all want to inhabit. Benchmarking—the practical, embodied work of exploration and mediation—is an attempt to find our way towards such a world.
