The tech sector is having a big 2024. Nvidia just crushed earnings expectations. The artificial intelligence boom remains in full swing. The tech-heavy Nasdaq index is up more than 8 percent year to date.

The U.S. economy is also doing surprisingly well, adding 353,000 jobs in January, well ahead of economists' forecasts. Hotter-than-expected inflation data may also keep the Fed from cutting rates as soon as the market expects, a sign that the economy remains strong enough to support tighter monetary policy for longer.

It's a different story for tech workers, though.

"The layoffs to the start of 2024 signal a dramatic shift in the tech industry," said Jeff Shulman, professor at the University of Washington's Foster School of Business. "We're going to continue to see layoffs happen as the future of work has changed, as the future of technology has changed and as investors' appetite for risk and growth versus profitability has dramatically changed as well."
