Tech companies are slashing thousands of jobs as they pivot toward AI
Technology companies are investing heavily in artificial intelligence, and some workers are already paying the price.
SAP is the latest big tech player to cut jobs as it pours money into AI, with the German software giant announcing this week that it is investing more than $2 billion to integrate artificial intelligence into its business as part of what it called “transformation program.” At the same time, the company said Tuesday it plans to restructure 8,000 roles. Some of the workers will be laid off, while others will be re-trained to work with AI.
The company said it expects to employ roughly the same number of workers at year’s end as it does now.
SAP is not an outlier. In the little more than a year since generative AI tools like ChatGPT, based on so-called large language model technology, have been available to the public, a number of large tech companies have announced plans to plunge into AI — job cuts often follow.
“I would counsel folks to watch what the firms do, and if they are saying the presence of large language models is allowing them to lay people off, that has to be taken into account,” said Mark Muro, a senior fellow at the Brookings Institution who studies the interplay between technology and people. “There is no doubt forthcoming work is going to show that coding and many engineering type occupations have very high exposure levels [to AI]. So we should take them at face value on this.”
Last week, Alphabet-owned Google said it laid off hundreds of workers from its ad sales team as it further invests in AI. Although Google did not directly attribute the layoffs to AI, in a memo to employees obtained by Business Insider Google’s chief business officer, Philipp Schindler, referred to the “profound moment we’re in with AI” in announcing the cuts.
Microsoft is also doubling down on AI, investing billions in ChatGPT maker OpenAI, as it slashes jobs. And language learning platform Duolingo acknowledged a 10% reduction in its contractor workforce at the end of 2023, but denied that all of the cuts were related to increased AI usage.
“In some cases, this was because the contractor’s project concluded, and in some cases this was because the contractor’s work was no longer needed due to changes in how we generate and share content between our 100+ language courses,” a spokesperson told CBS MoneyWatch.
Duolingo added that it does sometimes use AI to generate sentences and translations and that AI can help contractors work faster.
Is AI already replacing people?
To be sure, some of the companies are redirecting their investments into AI while cutting spending in other areas of their business, leading to layoffs. Columbia University business professor Oded Netzer cautioned against lining rising corporate investment in AI to worker layoffs.
“We know 2023 was the year of generative AI and companies invested in it heavily,” he told CBS MoneyWatch. “That means there are some jobs they’ve decided to invest less in, and they may be laying off workers. But it also means the jobs they’re hiring for are related to AI. That’s not to say AI replaces jobs.”
In Netzer’s view, companies are simply doing what they typically do — hiring more workers that specialize in fast-growing parts of the business, while laying off those whose skills may be less useful or contribute less to revenue growth. For example, he said, as Microsoft invests in AI it might decide to scale back its production of computer hardware, like keyboards.
Still, recent tech layoffs may be a troubling sign for employees who were told that AI would eliminate some of the rote work associated with their jobs, freeing them up to engage in more creative or productive work. Because technology is diffused across all types of companies in different sectors, big tech corporations can serve as a bellwether for the rest of the economy.
“All sort of firms use digital technologies, so I think this is a sobering signal. It does appear these impacts are occurring quite rapidly,” Muro of Brookings said.
Eliminating workers as they invest in AI is “low hanging fruit” for companies, he added. Yet a lot remains to be seen about how the AI revolution plays out in the workplace.
“A lot of training and re-skilling may be a common outcome. There may be some layoffs with the enhancement of other jobs,” he said.
Cory Stahle, an economist at the Indeed Hiring Lab, told CBS MoneyWatch that AI tools are not yet sophisticated enough to replace workers entirely. They may be able to perform certain job functions, but still require human input and supervision. The layoffs are also likely tied to companies consolidating their workforces after going on hiring sprees during the pandemic, he added.
“They are rebalancing after the huge hiring burst we saw couple years back during the pandemic when people were at home, consuming more tech products than they normally would have,” Stahle said. “Now they are back out flying and staying at hotels, and the shift in consumer demand is necessitating an adjustment at these tech companies.”
If AI were really the culprit, layoffs would be far more widespread across diverse industries, according to Stahle. “And we haven’t seen that happen yet,” he said.

New discoveries could rewrite the history of early Americans — and the 4-ton sloths they lived with
Sloths weren’t always slow-moving, furry tree-dwellers. Their prehistoric ancestors were huge – up to 4 tons – and when startled, they brandished immense claws.
For a long time, scientists believed the first humans to arrive in the Americas soon killed off these giant ground sloths through hunting, along with many other massive animals like mastodons, saber-toothed cats and dire wolves that once roamed North and South America.
But new research from several sites is starting to suggest that people came to the Americas earlier – perhaps far earlier – than once thought. These findings hint at a remarkably different life for these early Americans, one in which they may have spent millennia sharing prehistoric savannas and wetlands with enormous beasts.
“There was this idea that humans arrived and killed everything off very quickly – what’s called ‘Pleistocene overkill,'” said Daniel Odess, an archaeologist at White Sands National Park in New Mexico. But new discoveries suggest that “humans were existing alongside these animals for at least 10,000 years, without making them go extinct.”
Some of the most tantalizing clues come from an archaeological site in central Brazil, called Santa Elina, where bones of giant ground sloths show signs of being manipulated by humans. Sloths like these once lived from Alaska to Argentina, and some species had bony structures on their backs, called osteoderms – a bit like the plates of modern armadillos – that may have been used to make decorations.

In a lab at the University of Sao Paulo, researcher Mírian Pacheco holds in her palm a round, penny-sized sloth fossil. She notes that its surface is surprisingly smooth, the edges appear to have been deliberately polished, and there’s a tiny hole near one edge.
“We believe it was intentionally altered and used by ancient people as jewelry or adornment,” she said. Three similar “pendant” fossils are visibly different from unworked osteoderms on a table – those are rough-surfaced and without any holes.
These artifacts from Santa Elina are roughly 27,000 years old – more than 10,000 years before scientists once thought that humans arrived in the Americas.
Originally researchers wondered if the craftsmen were working on already old fossils. But Pacheco’s research strongly suggests that ancient people were carving “fresh bones” shortly after the animals died.
Her findings, together with other recent discoveries, could help rewrite the tale of when humans first arrived in the Americas – and the effect they had on the environment they found.
“There’s still a big debate,” Pacheco said.
“Really compelling evidence”
Scientists know that the first humans emerged in Africa, then moved into Europe and Asia-Pacific, before finally making their way to the last continental frontier, the Americas. But questions remain about the final chapter of the human origins story.
Pacheco was taught in high school the theory that most archaeologists held throughout the 20th century. “What I learned in school was that Clovis was first,” she said.
Clovis is a site in New Mexico, where archaeologists in the 1920s and 1930s found distinctive projectile points and other artifacts dated to between 11,000 and 13,000 years ago.
This date happens to coincide with the end of the last Ice Age, a time when an ice-free corridor likely emerged in North America – giving rise to an idea about how early humans moved into the continent after crossing the Bering land bridge from Asia.

And because the fossil record shows the widespread decline of American megafauna starting around the same time – with North America losing 70% of its large mammals, and South America losing more than 80% – many researchers surmised that humans’ arrival led to mass extinctions.
“It was a nice story for a while, when all the timing lined up,” said paleoanthropologist Briana Pobiner at the Smithsonian Institution’s Human Origins Program. “But it doesn’t really work so well anymore.”
In the past 30 years, new research methods – including ancient DNA analysis and new laboratory techniques – coupled with the examination of additional archaeological sites and inclusion of more diverse scholars across the Americas, have upended the old narrative and raised new questions, especially about timing.
“Anything older than about 15,000 years still draws intense scrutiny,” said Richard Fariña, a paleontologist at the University of the Republic in Montevideo, Uruguay. “But really compelling evidence from more and more older sites keeps coming to light.”
In Sao Paulo and at the Federal University of Sao Carlos, Pacheco studies the chemical changes that occur when a bone becomes a fossil. This allows her team to analyze when the sloth osteoderms were likely modified.
“We found that the osteoderms were carved before the fossilization process” in “fresh bones” – meaning anywhere from a few days to a few years after the sloths died, but not thousands of years later.
Her team also tested and ruled out several natural processes, like erosion and animal gnawing. The research was published last year in the journal Proceedings of the Royal Society B.
One of her collaborators, paleontologist Thaís Pansani, recently based at the Smithsonian Institution, is analyzing whether similar-aged sloth bones found at Santa Elina were charred by human-made fires, which burn at different temperatures than natural wildfires.
Her preliminary results suggest that the fresh sloth bones were present at human campsites – whether burned deliberately in cooking, or simply nearby, isn’t clear. She is also testing and ruling out other possible causes for the black markings, such as natural chemical discoloration.
“A giant ground sloth”
The first site widely accepted as older than Clovis was in Monte Verde, Chile.
Buried beneath a peat bog, researchers discovered 14,500-year-old stone tools, pieces of preserved animal hides, and various edible and medicinal plants.
“Monte Verde was a shock. You’re here at the end of the world, with all this organic stuff preserved,” said Vanderbilt University archaeologist Tom Dillehay, a longtime researcher at Monte Verde.
Other archaeological sites suggest even earlier dates for human presence in the Americas.
Among the oldest sites is Arroyo del Vizcaíno in Uruguay, where researchers are studying apparent human-made “cut marks” on animal bones dated to around 30,000 years ago.
At New Mexico’s White Sands, researchers have uncovered human footprints dated to between 21,000 and 23,000 years ago, as well as similar-aged tracks of giant mammals. But some archaeologists say it’s hard to imagine that humans would repeatedly traverse a site and leave no stone tools.

“They’ve made a strong case, but there are still some things about that site that puzzle me,” said David Meltzer, an archaeologist at Southern Methodist University. “Why would people leave footprints over a long period of time, but never any artifacts?”
Odess at White Sands said that he expects and welcomes such challenges. “We didn’t set out to find the oldest anything – we’ve really just followed the evidence where it leads,” he said.
While the exact timing of humans’ arrival in the Americas remains contested – and may never be known – it seems clear that if the first people arrived earlier than once thought, they didn’t immediately decimate the giant beasts they encountered.
And the White Sands footprints preserve a few moments of their early interactions.
As Odess interprets them, one set of tracks shows “a giant ground sloth going along on four feet” when it encounters the footprints of a small human who’s recently dashed by. The huge animal “stops and rears up on hind legs, shuffles around, then heads off in a different direction.”
