[01:29:09] S1: What does EVT stand for? [01:29:11] S0: It stands for when we compile the hardware for the first time with everything that's supposed to be done. So final components, final materials, you're making the components on the tools, you're going to make them for mass production instead of just machining them. So it's a big deal. And so what we had to do was favor or prioritize. We had four floating cameras. We had to lock the bottom two to each other and put them on a bracket so that the relative distance from them met the spec that he needed and then let the other two float. So this was an architectural change. And this was a failure. I mean, it was a failure in understanding the spec. It was a failure in essentially the product design, but it was because of a misunderstanding of the spec. And so we were able to adapt. We actually kept the build on time and we actually shipped the product on time, but it was really stressful. And it turned out that actually the new design was better because with a favored pair, you have source of truth for the space and then the other two cameras overlap onto that source of truth. And so it worked well. I thought it was a good outcome, but it was a scramble and certainly wish that we caught it four months earlier. [01:30:30] S1: Another example of just how hard hardware is, just like you mess up a spec and like, all right, here, we wasted a week building something that didn't work and now it's like four months later still having to redo the hardware supply chain. [01:30:41] S0: Yeah. It was tricky.

[01:30:41] S0: Yeah. It was tricky. [01:30:43] S1: So the Quest 2 that shipped was this with the cameras moved. [01:30:47] S0: Yeah. If you look, the cameras have, there's two cameras a little closer to one another in the front of the Quest than at the bottom. [01:30:53] S1: Wow. How did Bos and Zuck feel about this? [01:30:59] S0: The fact that I don't remember probably means it was okay. I think we addressed it, we redesigned it. We had to change the material and the bracket. I think we had to make steel to hold the tolerance we needed. But it worked out and the price and the cost and yields were fine. So I think we adapted. [01:31:18] S1: And that was the bestselling VR device of all time. Is that right? [01:31:21] S0: I think it was. [01:31:21] S1: Okay. [01:31:22] S0: I don't have the final sales numbers, but yeah. [01:31:24] S1: Okay [inaudible 01:31:25]. Okay. Caitlin, we've covered so much ground. Is there anything else you wanted to share? Anything else you want to leave listeners with? Either double down something we've shared or anything else that's just like, "Oh, here's something I want to share."

[01:31:24] S1: Okay [inaudible 01:31:25]. Okay. Caitlin, we've covered so much ground. Is there anything else you wanted to share? Anything else you want to leave listeners with? Either double down something we've shared or anything else that's just like, "Oh, here's something I want to share." [01:31:38] S0: I think that this is probably one of the most exciting times we're coming into, and it's normal I think for all of us, myself included, to be worried and scared about it, but I also think it's an opportunity for people to have an extraordinary amount of progress and be able to as an individual do more than we've ever done before. And so that's the side I'm trying to embrace. These new tools, this new way of work is scary, but if you embrace it and are daily using these AI tools right now and daily applying them to what you're doing, you'll be at the forefront of whatever comes next. And so I just want to encourage everyone to be creative, use these tools, have fun with them, figure out what the boundaries are, and then every time a new model comes out, test again because it's really important to know what we're dealing with and where these boundaries are. But I've never been more excited about the power of an individual. [01:32:35] S1: Well, with that, Caitlin, we've reached our very exciting lightning round. I've got five questions for you. Are you ready? [01:32:41] S0: I'm ready. [01:32:42] S1: First question, what are two or three books that you find yourself recommending most to other people?
01:32:42 · Lenny Rachitsky, Caitlin Kalinowski
[01:32:42] S1: First question, what are two or three books that you find yourself recommending most to other people? [01:32:46] S0: I've been mostly reading the classics lately. Book of the New Sun is a great fiction book, which I really recommend. I think that's what it's called. I haven't read it in a little while. I love Mrs. Dalloway. Actually, I think it's a very interesting book about transitions, and it was a post-war book by Virginia Woolf. So I really love it and I think it's really wonderful. I think Herodotus Histories is pretty incredible. He's wrong a lot, but he's also, it's the first history book and in many cases he's going and finding firsthand or secondhand accounts of what happens. It's a way to look into the world at a completely different era than it is now. So these are some books that I like, and I'll double check the title of the first one and email you, but I think that's what it's called. [01:33:36] S1: Okay. And we'll link to the correct one in the show notes. Favorite recent movie or TV show that you have really enjoyed? [01:33:43] S0: I'm really into Euphoria right now. I think the new Euphoria, I'm interested in the characters and figuring that out, what's going to happen there. [01:33:56] S1: That show's so stressful whenever I watch. [01:33:59] S0: It's a melodrama. I think you have to think about it as a soap opera and then it's fun. If you think about it too literally or practically-

[01:33:59] S0: It's a melodrama. I think you have to think about it as a soap opera and then it's fun. If you think about it too literally or practically- [01:34:05] S1: Okay. That's helpful. Do you have a favorite product you've recently discovered that you really love? Could be hardware, could be an app, could be a piece of clothing, could be a gadget. [01:34:14] S0: I really like Vollebak, the clothes. They make really interesting clothes. They're essentially basing their new clothes on material science. So they take new material science and make them into clothes. It's just a fun brand to follow. [01:34:26] S1: Vollebak. [01:34:27] S0: V-O-L-L-E-B- A-K. [01:34:31] S1: Vollebak. Very cool. Do you have a favorite life motto that you often come back to in work or in life? [01:34:38] S0: Have you seen that branch where there's all these branches and then you're here and then there's all these branches from this point? [01:34:43] S1: [inaudible 01:34:43], yeah. [01:34:45] S0: Yeah. You know who it's from. I didn't know who it was from. I think about it a lot because it's very hard not to get stuck in the future or the past and stay kind of here. I have trouble with that, but that is a great reminder that you get to pick every day. You get to decide every day what you want to do. And sometimes things don't go the way that you want and sometimes you regret what you did or sometimes you're proud of what you did, but it doesn't really matter. What matters is what's right in front of you.

I have trouble with that, but that is a great reminder that you get to pick every day. You get to decide every day what you want to do.

What matters is what's right in front of you. [01:35:11] S1: We'll either show that image on the screen as you say that or we'll link to it in the show notes. It's so powerful. Final question. Somebody that knows you well shared this really interesting tidbit about you, that you hired a PhD to tutor you on the staples of ancient Greece and Rome and just get really nerdy about this stuff. What's going on there? What drives you to go so deep on these sorts of things?
