Michael Calore: Hey Lauren, how are you doing?

Lauren Goode: I’m OK, Mike. It’s earnings season, so a lot of us on the business desk here at WIRED have been tuning into tech companies earnings reports and their earnings calls. And I guess that basically means it’s CapEx season.

Michael Calore: CapEx?

Lauren Goode: Capital expenditures.

Michael Calore: You say CapEx?

Lauren Goode: Yeah. Now that I’m a business desk reporter, I say CapEx.

Michael Calore: You’re one of those.

Lauren Goode: I throw it around at parties. No, I really don’t. But we are seeing a trend in how tech companies are sleeping on piles of money, but they aren’t just sleeping on it. They’re sharing big plans to spend on it, and especially to spend on AI infrastructure.

Michael Calore: Right. Data centers.

Lauren Goode: Yeah, more data centers. Not just data centers, but yes, that’s a big part of it.
