Sam Altman, the CEO of OpenAI, spends most of his time on podcasts. I don’t blame him. As the CEO of a company whose stated goal is to “change the way people work” by making work “easier, faster and more efficient,” he probably doesn’t have much else to do.

Altman has been vocal about his vision of the future and how OpenAI will usher in a change that, in his words, “will be at least as big as the internet, maybe bigger.” However, it seems his tone has shifted. Altman is no longer the doom-and-gloom A.I. prophet he was a few years ago, when he warned Congress that A.I. would fundamentally change the world, creating an opportunity for bad actors if America wasn’t quick to invest in building its A.I. infrastructure before China.

Now, he seems to be pretty optimistic about this future, recently telling tech reporter Cleo Abram that Gen Z is actually super lucky to be staring down the direct impact of his company’s new technology, saying that if he were a recent graduate, he’d “feel like the luckiest kid in all of history.”

Which is a hilarious thing to say, just 24 hours after addressing concerns that the public is becoming too attached to “specific A.I. models.”
