  • Sequoia Capital, calculated that investments in A.I. were running short of projected profits by a margin of at least several hundred billion dollars annually. (He called this “A.I.’s $600 billion question” and warned of “investment incineration.”)
  • In a similarly bearish Goldman Sachs report, the firm’s head of global equity research estimated that the cost of A.I. infrastructure build-out over the next several years would reach $1 trillion. “Replacing low-wage jobs with tremendously costly technology is basically the polar opposite of the prior technology transitions I’ve witnessed,” he noted. “The crucial question is: What $1 trillion problem will A.I. solve?”

  • “A.I. slop”: often uncanny, frequently misleading material, now flooding web browsers and social-media platforms like spam in old inboxes. Years deep into national hysteria over the threat of internet misinformation pushed on us by bad actors, we’ve sleepwalked into a new internet in which meaningless, nonfactual slop is casually mass-produced and force-fed to us by A.I.

  • while the internet was never perfectly trustworthy, one epoch-defining breakthrough of Google was that it got us pretty close.

  • Even in describing regular old pollution, this framework has its shortcomings, especially because it treats as automatic eventual progress that has always required tooth-and-nail fights against some very stubborn bad actors
  • A.I. is generating an awful lot of genuine pollution, too — both Google and Microsoft, which each pledged in 2019 to reach zero emissions by 2030, have instead expanded their carbon footprints by nearly 50 percent in the interim.

What Gives Poor Kids a Shot at Better Lives? Economists Find an Unexpected Answer - WSJ - 0 views

poor employment income research economics social mobility mobility social

  • For all our divisions, Americans have been united by a singular obsession: How can we have a better life? Economists call this economic mobility—the ability to move up the income ladder and make it to a higher rung than your parents.
  • Harvard University economist Raj Chetty has spent more than a decade working to understand what makes mobility possible, and why in some places the children of poor parents have been more able to move up than in others.
  • Using anonymized census and tax data, Chetty and his fellow researchers have been able to follow millions of Americans from childhood into adulthood. The data showed that even in neighborhoods bordering one another, outcomes for poor children can be vastly different.
  • ...15 more annotations...
  • Analyzing data covering a near universe of Americans born from 1978 to 1992, the researchers found that when employment among the poor parents of children in a community improves, those children are better off economically as adults
  • it doesn’t rely on whether a child’s own parents are employed: Outcomes also improve for children who simply grow up in a neighborhood where more parents have jobs. In other words, their own parents might be unemployed, but if their schoolmates’ parents work, their outcomes will be better.
  • : In places where parental employment deteriorates, the opposite happens—children do worse as adults.
  • “Growing up in a community where employment rates are higher for people in your race and class—if those employment rates are higher, the kids who grew up in those environments do better in the long run,”
  • For poor white children born in 1978, vast swaths of the U.S. were a land of opportunity. Apart from some areas, such as Appalachia and Rust Belt areas of Michigan and Ohio, these children overall had a good chance of making it to a higher rung on the income ladder than their parents. 
  • For poor white children born in 1992, the map was more constrained. While some parts of America, such as the upper Midwest, remained bastions of opportunity, much of the U.S. did worse. Children with parents at the 25th percentile who grew up in Milwaukee had lower income when they turned 27 in 2019—an inflation-adjusted $30,619—than their older counterparts had.
  • This dynamic, playing out across the country, led to a significant widening of the income gap between poor and well-off white children. A white child born to parents at the 25th percentile in 1978 made, on average, an inflation-adjusted $10,383 less at age 27 than a child born to parents at the 75th percentile. But for children born in 1992, that income difference was 27% larger at $13,202.
  • In contrast to the environment for poor white children, few places in America provided poor Black children born in 1978 much opportunity for advancement.
  • Kent County, Mich., is a little more than 100 miles directly east of Milwaukee, and home to Grand Rapids, another old-line manufacturing city. Black children born to parents at the 25th percentile by income in 1978 who grew up in Kent had an average household income of $17,029 at age 27. That put them at the 28th percentile by income, leaving them on essentially the same rung as their parents.
  • But poor Black children born in 1992 who grew up in Kent County did better. On average, a Black child at the 25th percentile in that birth cohort had inflation-adjusted household income of $23,547 at age 27, or 38% more than their 1978 counterpart. 
  • One thing that changed for poor white children compared with poor Black children was the relative share of their parents who were employed. 
  • In Milwaukee County, for example, the share of the parents of low-income white children who were employed went from 69.1% for children born in 1978 to 55.6% for children born in 1992—a 13.5 percentage point decline. Those employment declines were likely driven by the loss of more than a third of the county’s manufacturing jobs during those years. Children born at the 25th percentile in 1992 reached the 44th percentile on average, 4 percentage points lower than those born in 1978.
  • And this pattern of falling parental employment and worsening outcomes repeated itself across much of the country. In counties where employment rates among poor white parents fell sharply, such as Philadelphia County, Pa., the income ranks of poor white children in adulthood fell too. Mobility tended not to deteriorate as much for poor white children growing up in counties such as Sumner, Tenn., where parental employment held up better.
  • the experience in Kent was the general pattern across the country, with employment rates for the parents of poor Black children falling less than their poor white counterparts, or gaining. And as was the case with poor whites, the new research finds that changes in parental employment rates in a community were strongly associated with changes in children’s outcomes.
  • the researchers emphasize that it is not a zero-sum game, with mobility for poor Black people improving only because mobility for poor white people is falling: Indeed, places where opportunity for Black children improved most are also where white children did best.

Israeli Military Says Hamas Can't Be Destroyed, Escalating Feud With Netanyahu - WSJ - 0 views

  • A rift between Israeli Prime Minister Benjamin Netanyahu and the country’s military leadership is spilling increasingly into the open after the armed forces’ top spokesman said Netanyahu’s aim of destroying Hamas in Gaza is unachievable.“The idea that we can destroy Hamas or make Hamas disappear is misleading to the public,” military spokesman Daniel Hagari told Israeli television on Wednesday.
  • The exchange was an illustration of months of tensions between Netanyahu and the country’s military leadership, who argue that Hamas could only be defeated if Israel replaces it with another governing authority in Gaza. During more than eight months of war, the Israeli military has invaded swaths of the Gaza Strip, only to see Hamas reconstitute itself in areas when Israeli forces withdraw.“What we can do is grow something different, something to replace it,” Hagari said Wednesday. “The politicians will decide” who should replace Hamas, he said.
  • The friction between Netanyahu and the military establishment had burst into public view earlier in the war. In May, Defense Minister Yoav Gallant delivered a speech calling on the government to decide who should replace Hamas in Gaza. The lack of a decision, he said, left Israel with only two choices: Hamas rule or a complete Israeli military takeover of the strip.

  • The Israeli military relies on reservist soldiers, some of whom have described growing exhaustion as Israel manages conflicts for months on end on multiple fronts, including the border with Lebanon and in the West Bank. An end to fighting in Gaza would give Israeli forces a respite that analysts say is needed, especially if fighting with Hezbollah escalates further.
  • Israel Ziv, a retired Israeli general and veteran of multiple wars, said tensions between the Israeli military and security establishment and Netanyahu are at a record high.“The IDF feels and the security echelon feels that we exhausted the purpose of the war. We reached the maximum tactical peak that we can achieve,” he said. “As long as Rafah was there, they could say finish the job. OK it’s finished now.”
  • Netanyahu has rejected a series of proposals for possible alternatives to Hamas, including an American plan to bring in the Palestinian Authority and Arab calls for a Palestinian unity government that would include Hamas. Some military analysts and former Israeli officials have questioned whether installing a new government in Gaza was ever possible, given that Hamas has managed to survive the Israeli military assault.
  • “We need to make a decision,” said Ziv. “Even a bad decision, that’s OK. Let’s say [we] occupy Gaza in the next few years because we need to clear up the last few terrorists. OK, it’s a bad decision, but it’s a decision. The military needs to know.”
  • The dispute between Netanyahu and the military centers in part on how officials define a defeat of Hamas. An Israeli military official said the army considers a battalion “dismantled” not when all its fighters are killed, but when its command structure and ability to carry out organized attacks are eliminated. 
  • Military analysts say that Hamas’s militia forces are likely to survive the Israeli military operation even in Rafah, in part because the Israeli army’s approach leaves many lower-ranking Hamas fighters in place. Hamas’s top leadership in the enclave, including its leader, Yahya Sinwar, have also eluded Israeli forces throughout the war.
  • “Hamas is preserving its forces in Rafah rather than engaging the Israel Defense Forces, likely because Hamas does not believe Israel’s Rafah operation will be decisive,” said an assessment this week from the Institute for the Study of War and the American Enterprise Institute’s Critical Threats Project.
