The big spend Danist Soh When OpenAI released its ChatGPT-3 chatbot in November 2022, it sent a shock wave around the world. Here was a machine that looked a lot like the artificial intelligence many had been imagining for generationsânot least through science fiction like 2001: A Space Odyssey, Blade Runner, or The Matrix. ChatGPT also sent a hype wave across the tech industryâleading even to predictions that AI would soon be on its way to replacing most human work. An enormous investment boom followed. Over the next couple of years, tech firms are on track to spend more than US$1 trillion on AI. This year, theyâve already spent hundreds of billions. Microsoft alone is set to invest more than $55 billionâmore than the gross domestic product of Tunisia or Latvia. But as money followed the exhilaration, skepticism is now following the money. Some investors say the industryâs high stock prices are a bubble, soon to burst. Others wonder where AI's âkiller appâ isâor whether oneâs ever coming. Meanwhile, all this new computing power is straining electricity grids, as AI firms build enormous new data centersâwhich, worldwide, use as much electricity as Italy every yearâand driving carbon-dioxide emissions. Now, the stock market appears to be siding with the skeptics. Shares in AI and tech firms dove throughout late August and early September. Executives at top investment firms like Goldman Sachs openly doubt AIâs long-term economic prospects. And analysts are forecasting that OpenAI will lose around $5 billion in 2024. Whatâs happened? Daron Acemoglu is a professor of economics at MIT and a co-author of the 2023 book [Power and Progress: Our 1,000-Year Struggle Over Technology and Prosperity](. Acemoglu says AI has a basic economic problem: Its chatbots and other apps donât generate enough revenue to cover the massive investments theyâre built withâand they arenât likely to any time soon. More fundamentally, the AI industry is struggling against all the expectations that have driven so much investment in it: Itâs supposed to be revolutionary, but it still canât build models that do even passably well what humans are distinctively good atâsolving complex problems and doing complex tasks. But because of the way the industry thinks about itself, thatâs not slowing it down ...

Advertisement From Daron Acemoglu at The Signal: - âA lot of people in the industry believe theyâre marching fast toward artificial general intelligenceâAGIâwhich could âthinkâ and reason like humans. They also believe in what economists call scaling laws: They think they can quickly double computing capacity, double the amounts of data they feed into their models, and double those modelsâ intelligenceâhowever they define that. They think itâs all money well spent. If they could, theyâd spend far more.â - âBusiness leaders in the United States are under tremendous pressure to invest in AI. Theyâre continuously told by those who follow AI that if youâre not ahead of your competitors in AI, then youâre effectively dying. So companies are scrambling to weave AI into their operations, but itâs just not clear how to do that at scale. Even if a killer app comes out, these companies will still need time to figure out how to integrate it without upending their businesses.â - âThereâs a lot of hype. Iâm not ready to call it a stock-market bubble. If you say itâs a bubble, youâre saying it probably wonât be long before it bursts. But thatâs not something Iâd say, because these market trends are going to continue as long as people keep investing in AI. Ultimately, though, this investment isnât sustainable.â [Read on]( The world is complex, rapidly changing, and inherently uncertain ⦠Thatâs why we look at it the way a detective would: Everything The Signal does starts with good questions, and every answer leads us to more of them.

NOTES The resurgence of child poverty in America Annie Spratt Last week, the United States Census Bureau published its latest accounting of the U.S. population. Among its more sobering statistics: Between 2022 and 2023, child poverty in the country rose from 12.5 to 13.7 percent, representing some 979,000 more children now living in povertyâand bringing the total to nearly 10 million. What may be most striking about [these numbers](: In 2021, U.S. child poverty was near historic lowsâat 5.2 percent. What happened? Before the Covid-19 pandemic, the child-poverty rate was close to what it is now. The U.S. government expanded the child tax credit to help Americans through, giving many families a monthly $300 per child. That moved around three million kids out of povertyâand when the expansion lapsed in 2022, the child poverty rate rebounded. Now, both the Democratic and Republican presidential campaigns are floating proposals to reintroduce an expanded child tax credit. Kamala Harris is promising to bring it back in a more generous formâoffering lower- and middle-income parents $6,000 in the first year of their childâs life. Donald Trump hasnât tabled a specific proposal himself; his running mate J.D. Vance, however, has suggested $5,000. Of course, itâs campaign season. But consensus between the campaigns on an idea like thisâthatâs notable. âGustav Jönsson [Explore Notes]( Want more?
