Marketplace’s Meghan McCarty Carino speaks with Paul Vixie, vice president at AWS Security and an early internet innovator, about the rapid buildout of fiber optic networks during the dot-com boom, and what happened when the bubble burst.

529 Bryant St. in Palo Alto, California, is home to a key landmark in tech history. Now owned and operated as a data center by Equinix, the building has been a networking hub to a variety of firms, including the earliest telephone switch board operators and early internet firms like Alta Vista. Marketplace’s Meghan McCarty Carino visited the data center to learn more.

Billions of dollars has been poured into the AI economy in recent years. As part of a new series about what the AI economy means for you, Marketplace Tech is looking at the infrastructure build-out behind the AI boom, starting with a visit to an Amazon Web Service lab in Cupertino, California, where AWS developers are squeezing as much networking efficiency out of their servers as possible for their AI ambitions.

A Micron memory chip factory in upstate New York is wrangling with local groups who want legal assurances the project will benefit the local community. Plus, YouTube plans to crack down on AI slop.

But first, it's shaping up to be a big year for very big initial public offerings. Elon Musk is reportedly preparing to take SpaceX public at an anticipated valuation of around $1.5 trillion. AI companies Anthropic and OpenAI are also expected to follow suit this year.

Marketplace’s Meghan McCarty Carino spoke with Paresh Dave, senior writer at Wired, to discuss all these topics on this week’s “Marketplace Tech Bytes: Week in Review.”

In the era of AI, sometimes a story is really just too good to be true, even if the initial evidence suggests otherwise.

But whether they know it or not, they’re also contending with “surveillance pricing,” where companies use personalized consumer data to serve up personalized prices. Marketplace's Kristin Schwab reports.

In an industry known for pushing the bounds of human innovation, tech elites are now trying to push the bounds of their own bodies. The hot new biohacking trend is injectable peptides — similar to the ones found in GLP-1 medications like Ozempic. But these are not approved by the Food and Drug Administration.

These gray-market peptides, largely from Chinese manufacturers, are being used by tech workers and founders. Not just to lose weight, but to optimize their health and performance in all manner of ways. “Marketplace Tech” host Meghan McCarty Carino speaks with independent journalist Jasmine Sun, who recently wrote about this for the New York Times.
