“If the world’s 223 international undersea cable systems were to suddenly disappear, only a minuscule amount of this traffic would be backed up by satellite, and the Internet would effectively be split between continents”*…
Your correspondent is hitting the road, so (Roughly) Daily will be a good bit more roughly than daily for a bit. Regular service should resume on or around May 6. Meantime, a fascinating– and meaty– piece to hold you…
Josh Dzieza goes deep on an undersung technology and the folks who keep it functioning…
The world’s emails, TikToks, classified memos, bank transfers, satellite surveillance, and FaceTime calls travel on cables that are about as thin as a garden hose. There are about 800,000 miles of these skinny tubes crisscrossing the Earth’s oceans, representing nearly 600 different systems, according to the industry tracking organization TeleGeography. The cables are buried near shore, but for the vast majority of their length, they just sit amid the gray ooze and alien creatures of the ocean floor, the hair-thin strands of glass at their center glowing with lasers encoding the world’s data.
If, hypothetically, all these cables were to simultaneously break, modern civilization would cease to function. The financial system would immediately freeze. Currency trading would stop; stock exchanges would close. Banks and governments would be unable to move funds between countries because the Swift and US interbank systems both rely on submarine cables to settle over $10 trillion in transactions each day. In large swaths of the world, people would discover their credit cards no longer worked and ATMs would dispense no cash. As US Federal Reserve staff director Steve Malphrus said at a 2009 cable security conference, “When communications networks go down, the financial services sector does not grind to a halt. It snaps to a halt.”
Corporations would lose the ability to coordinate overseas manufacturing and logistics. Seemingly local institutions would be paralyzed as outsourced accounting, personnel, and customer service departments went dark. Governments, which rely on the same cables as everyone else for the vast majority of their communications, would be largely cut off from their overseas outposts and each other. Satellites would not be able to pick up even half a percent of the traffic. Contemplating the prospect of a mass cable cut to the UK, then-MP Rishi Sunak concluded, “Short of nuclear or biological warfare, it is difficult to think of a threat that could be more justifiably described as existential.”
Fortunately, there is enough redundancy in the world’s cables to make it nearly impossible for a well-connected country to be cut off, but cable breaks do happen. On average, they happen every other day, about 200 times a year. The reason websites continue to load, bank transfers go through, and civilization persists is because of the thousand or so people living aboard 20-some ships stationed around the world, who race to fix each cable as soon as it breaks…

As we dive deep, we might send effectively-transmitted birthday greetings to a pioneer of telecommunications, Granville Woods; he was born on this date in 1856. An inventor, he held more than 50 patents, for innovations that ranged from a locomotive steam boiler to an egg incubator. But he is probably best remembered for his Synchronous Multiplex Railway Telegraph, a variation of the induction telegraph that relied on ambient static electricity from existing telegraph lines, allowing railroads to send messages between train stations and moving trains.
He is often referred to as the first African American mechanical and electrical engineer after the Civil War and as “the Black Edison” (sic).

Further to yesterday’s post on the poverty created by manufacturing displacement, and in the wake of the sturm und drang occasioned by the coup at OpenAI, the estimable Rana Foroohar on the politics of AI…
… Consider that current politics in the developed world — from the rise of Donald Trump to the growth of far right and far left politics in Europe — stem in large part from disruptions to the industrial workforce due to technology and globalisation. The hollowing out of manufacturing work led to more populist and fractious politics, as countries tried (and often failed) to balance the needs of the global marketplace with those of voters.
Now consider that this past summer, the OECD warned that white-collar, skilled labour representing about a third of the workforce in the US and other rich countries is most at risk from disruption by AI. We are already seeing this happen in office work — with women and Asians particularly at risk since they hold a disproportionate amount of roles in question. As our colleague John Burn-Murdoch has charted [image above], online freelancers are especially vulnerable.
So, what happens when you add more than three times as many workers, in new subgroups, to the cauldron of angry white men that have seen their jobs automated or outsourced in recent decades? Nothing good. I’m always struck when CEOs like Elon Musk proclaim that we are headed towards a world without work as if this is a good thing. As academics like Angus Deaton and Anne Case have laid out for some time now, a world without work very often leads to “deaths of despair,” broken families, and all sorts of social and political ills.
Now, to be fair, Goldman Sachs has estimated that the productivity impact of AI could double the recent rate — mirroring the impact of the PC revolution. This would lead to major growth which could, if widely shared, do everything from cut child poverty to reduce our burgeoning deficit.
But that’s only if it’s shared. And the historical trend lines for technology aren’t good in that sense — technology often widens wealth disparities before labour movements and government regulation equalise things. (Think about the turn of the 20th century, up until the 1930s). But the depth and breadth of AI disruption may well cause unprecedented levels of global labour displacement and political unrest.
I am getting more and more worried that this is where we may be heading. Consider this new National Bureau of Economic Research working paper, which analyses why AI will be as transformative as the industrial revolution. It also predicts, however, that there is a very good chance that it lowers the labour share radically, even pushing it to zero, in lieu of policies that prevent this (the wonderful Daron Acemoglu and Simon Johnson make similar points, and lay out the history of such tech transformation in their book Power and Progress…
We can’t educate ourselves out of this problem fast enough (or perhaps at all). We also can’t count on universal basic income to fix everything, no matter how generous it could be, because people simply need work to function (as Freud said, it’s all about work and love). Economists and political scientists have been pondering the existential risks of AI — from nuclear war to a pandemic — for years. But I wonder if the real existential crisis isn’t a massive crisis of meaning, and the resulting politics of despair, as work is displaced faster than we can fix the problem…
Everyone’s worried about AI, but are we worried about the right thing? “The politics of AI,” from @RanaForoohar in @FT.

As we equilibrate, we might recall that it was on this date in 1874 that electrical engineer, inventor, and physicist Ferdinand Braun published a paper in the Annalen der Physik und Chemie describing his discovery of the electrical rectifier effect, the original practical semiconductor device.
(Braun is better known for his contributions to the development of radio and television technology: he shared the 1909 Nobel Prize in Physics with Guglielmo Marconi “for their contributions to the development of wireless telegraphy” (Braun invented the crystal tuner and the phased-array antenna); was a founder of Telefunken, one of the pioneering communications and television companies; and (as the builder of the first cathode ray tube) has been called the “father of television” (shared with inventors like Paul Gottlieb Nipkow).
