David Edgerton is Professor of History at Kings College London. His book Shock of the Old challenged the way we think about innovation, arguing that we systematically overvalue the new and ignore the old (including maintenance). He has also written importantly on the British ‘warfare state’ and his book The Rise and Fall of the British Nation argues Britain became a fundamentally national economy from 1940-1985. In this conversation we discussed the uses of history in understanding AI and society, why the word ‘technology’ might mislead more than clarify and what a detailed material understanding of our world might look like. Philip Bell: David, you are a professor of history at King’s, and I think I’m right in saying you founded the Centre for the History of Science, Technology and Medicine at Imperial College London. In the foreword to Jean-Baptiste Fressoz’s new book, More and More and More, he describes it as coming out of the intellectual environment at Imperial, because I think he was a researcher there as well. It’s an absolute pleasure to have you on the podcast. Thank you for joining. David Edgerton: My pleasure. Philip Bell: The genesis of this conversation was the use of history and historical analogy in understanding what might inadequately be called technology. One thing I’ve found quite interesting about AI is that there seems to be a geopolitical divide in how it’s considered in historical context. The US, and the West generally, tends to compare AI to the atom bomb or the Manhattan Project — an existential threat to be contained. Whereas Chinese companies and policymakers, if you look at the “AI Plus” strategy in China, tend to compare AI to electricity — more of a utility to be diffused. Do you think analogies are helpful in understanding technologies or technical change, or do historical analogies trap us into particular responses? David Edgerton: Clearly some analogies will be helpful and others won’t be. What’s interesting about analogies in this strange area — discussion of technology, where we don’t really know what it is — is that they are often very predictable. Comparing AI with the atomic bomb is just a replica of comparing the Human Genome Project with the Manhattan Project. Desperately unoriginal comparisons. Comparing things with electricity is a bit richer and not quite so common. Suggesting that artificial intelligence will cause an industrial revolution just like the Industrial Revolution of the eighteenth century — that’s a very, very common argument. Not a very helpful one. So we need to beware the analogies. We need to wise up to the small range of analogies that are in play, and to understand why they’re being used and what they’re being used for. Philip Bell: That’s an interesting point about the predictability of the analogies. I’ve looked up a list of different analogies that have been used with regard to AI. Sundar Pichai, the CEO of Google, described AI as “more profound than electricity or fire.” Yann LeCun, until recently head of AI at Meta, said the invention of the printing press is the closest historical parallel to AI. Alex Karp, CEO of Palantir, compared AI to the Manhattan Project. It’s interesting because technologists seem very interested in talking about history. It reminds me of the famous Keynes quote: “Practical men who believe themselves to be quite exempt from any intellectual influences are usually the slaves of some defunct economist.” How would a technologist go about getting a better historical framing? David Edgerton: Well, you say technologists — who are these people? They’re not necessarily technologists. They are figures associated with great enterprises. I think that’s an important distinction to make. Yes, there’s a nice little list of comparisons. It’s always the big ones, isn’t it? They could have said agriculture. They could have said the Neolithic Revolution, but that wouldn’t sound quite right, I guess. They are looking for big ones. And that’s all they’re trying to say: this is going to be big. So they search back — probably just Google — for other big changes in the past. They could have come up with the wheel, actually. Why is it fire and not the wheel? Why is it the Manhattan Project and not the project to build the B-29 bomber? It doesn’t mean anything. It’s not the product of research. It’s just a PR gambit. It’s not to be taken seriously; it’s just propaganda. Now, if one actually wanted to make a historical comparison, I guess first of all we wouldn’t, because AI hasn’t had a major impact yet. We have to start with a proper definition of what it is in the present that we want to compare with the past. Another way of looking at it: AI is, at the moment, very largely hype. So let’s look back at other cases of hype. Nuclear would be a very good example. The claim that nuclear would transform the world — that electricity produced by nuclear reactors would be “too cheap to meter.” Well, that didn’t happen. In fact, the Manhattan Project as a comparator is a very strange one, because if you take the Manhattan Project seriously — beyond just a kind of reference to big bangs and lots of money — we find that atomic bombs have not been used in war since 1945, and that the generation of electricity through atomic power has not in fact been that significant. We could easily have lived without nuclear power in the world. What is the story that’s been told? These aren’t proper histories; they’re other kinds of hype. Airplanes would bring world peace. Dynamite would lead to the end of war. There are lots of these. This is a very, very old way of thinking about this mysterious thing, “tech.” You’d have thought we’d get over it. But in some ways AI itself makes it worse, because if you were to ask AI — as the Tony Blair Institute did — what is the future of AI, it will just trawl through all the rubbish that’s online and tell you it’s going to be like the atomic bomb, or like fire, or like the Industrial Revolution. We are living in a kind of miasma of very bad, very cheap knowledge about these things. My immediate reaction is that none of this is to be taken seriously except as PR, except as lobbying. There’s no analytical intelligence behind any of these claims; there’s a political intelligence behind them. Philip Bell: That’s an interesting point about using AI to regurgitate historical analogies. I think Adam Tooze has described AI as a kind of “technology of technology,” which I thought was interesting. But in your book The Shock of the Old, I think you describe historians as the true experts of the future — please correct me if I’m wrong. In my experience studying history as an undergraduate, I took away two principles: the contingent nature of society, the fact that the past was continually surprising, which makes me think the future is likely to be surprising too; and also a kind of humility about the fact that people got lots of things wrong. Do you still believe that historians are the true experts of the future, and why? David Edgerton: Yes, I do. And you’ve already explained it. We’re the experts on the future because we have to train ourselves to remember the future isn’t here yet and we don’t know what it is. We have to train ourselves because, of course, we’re looking at the past and we know what’s going to happen next. So we’re always going to beware the idea that war was inevitable in 1939 or that India would get its independence in 1947. We are very used to the idea — or should be — that the future is not completely open-ended, but as you say, will very likely be surprising. Anyone who claims they know what the future is doesn’t know anything about the future for sure, and doesn’t know anything about history either. Philip Bell: I was thinking that in a way, then, it’s useful not to look too deeply into the past. If you have a particular functional reason for acting — let’s say you want to raise lots of capital in venture capitalism — maybe there’s a balance. If history does teach us to be slightly more hesitant about our predictions, that might be less useful for someone trying to raise billions of dollars. So maybe there’s a slight paradox where it’s functionally not helpful for some people to carefully examine the past? David Edgerton: No, exactly. But nobody is carefully examining the past. As I say, this isn’t serious. What is serious is that it’s PR — PR to investors in particular, PR to governments who have to support these new technologies. If you are a serious investor, would you look at historical analogies? Well, no — unless you’re doing it really, really seriously. You’ve got to look at the present, you’ve got to look at the technology, you’ve got to make guesses as to what is going to happen. I think the one lesson to take from history is that predictions are likely to be wrong. One very important reason is that new techniques aren’t exactly the same as old techniques. In what sense is AI like a steam engine or like electricity? You mentioned Adam Tooze referring to AI as a “technology of technology.” So it’s different in that sense. Now, I wouldn’t say it’s necessarily the first technology of technology. The very word “technology” means the study of the technical arts. It is a way of understanding that allows you to change the techniques we have — a generalised view of the capabilities of machines, processes, whatever. So that’s not new. And the processing of information is not new either — that’s been central to our lives for centuries. The capabilities change, of course; the kinds of sensors change. But every new technique is by definition new, so you’re not going to find an exact parallel in the past. Philip Bell: That reminds me — I was listening to Andrej Karpathy, who used to be head o
