The Xbox nearly destroyed Seamus Blackley. He is the physicist and inventor who convinced Bill Gates to let Microsoft build a game console, and the experience left him exhausted, betrayed, and certain that he had to leave the company. But Blackley is not a person who stays in one lane. He has also brought ancient Egyptian yeast back to life, grown cacao trees in a secret lab near Pasadena, and made chocolate that chef José Andrés called the best in the world. This episode of Core Memory is a conversation about all of it — the physics, the trauma, the corporate warfare, and the accidental discoveries that come from relentless curiosity.

The physics of survival

Blackley grew up in rural New Mexico in an abusive household. He did not recognize how abnormal his childhood was until his twenties, when he realized that other people’s mothers did not cut them with knives. The normalization of violence and instability, he says, turned out to be an accidental superpower. When he later entered theoretical high-energy physics at Tufts — after nearly flunking out — he found that the intellectual brutality of the field did not scare him. Peer review, where colleagues tear apart your work to find the truth, felt familiar. “Coming from a terrible home turns out to give you a lot of ability to deal with peer review,” he says.

Show Notes

This episode is nerd catnip unlike anything I’ve ever seen before.

Ashlee sat down with Seamus Blackley, who you might know as the man who talked Microsoft into building the Xbox. Nowadays, you can find Blackley in a Pasadena laboratory making the world’s best chocolate. If you’re just here for the cacao, well, we did a video on it.

Blackley grew up in rural New Mexico and studied electrical engineering, then physics, at Tufts University. He spent years working on titles you know and love, like Madden, and ones perhaps you don’t, like Jurassic Park: Trespasser, a flop notorious enough to earn him his first death threats.

Also, Ashlee is away for a few weeks on a big video shoot in India, which means I, Kylie, will be filling in on all the writing stuff. Now that you know who the voice of God is here, let’s get into the most important thing — what I think about this episode!

Blackley is totally captivating and eccentric, exactly the way you’d expect a physicist who builds holograms and runs a chocolate farm to be. He got deep in ways I didn’t expect, about his abusive childhood and what it was like working at Microsoft. I particularly loved this line from him:

“The khaki pants wearing guys, the lifers, they show up and we had fought them to keep them away from [the Xbox]. The more we kept them away from it, the more consumers got excited because we were talking about things with the power of Microsoft and not the b******t of Microsoft. That was incredibly effective. But it was exhausting and it was a conscious effort of will to fight it. At some point it was going to destroy me and I had to stop.”

Blackley seems to talk at 2x speed naturally, and I’m grateful for it, because he has no shortage of brain-exploding lore to fit into these 80 minutes. He describes his whole career as “one long tale of woe and rapid dancing in the face of failure,” which is a very modest way to describe inventing the Xbox, shepherding Guitar Hero into existence, and abducting Jimmy Fallon. You’ll have to listen for that last one.
