The biggest challenge in designing ChatGPT is balancing the needs of a billion users across an extreme spectrum of use cases—from casual personal questions to professional automation—while avoiding overwhelming anyone with complexity.

38:37>> That's a great question and it's a really fun part of the way we work. Um, I think that we have we have vastly different audiences, like really really different. I've never worked in this kind of quite quite a spread. Um, you know, like at Instagram, uh, I I I spent eight years working at Instagram, we had a billion user or billions of users, maybe. I don't actually know what

39:03they're at now, but it was a lot of people. Um, but the product was pretty simple and it was sort of, you know, a couple ways you could use it. We did think about like creators and, you know, larger accounts that had special needs, but this is like vastly different where you have someone who's, you know, using this to help them come up with the recipe to eat tonight. Um, or, you know,

39:25brainstorm their next haircut or something like that. And then there's uh somebody who's like transforming the way they're doing farming for their you know um their like you know helping to automate their farm in Japan or something right and uh it's just like the broadest spectrum ever. Um generally what we've seen is that um we we believe in this idea of this sort of capability overhang where the the

39:56product um you know like vast majority of the people are getting a sliver of the the true value that they could out of the bottle. Um that's not necessarily a bad thing. Many you know they're still getting tons of value. Um but we found that like we you know make sure to focus on creating a extremely simple, streamlined experience for for many many people. Um, and then we put like uh all

40:24of the, you know, cutting edge stuff. We also make make sure to give that and and make sure that's like really accessible for the people that care. The challenge of course is like not necessarily overindexing and and sort of like putting that putting uh something that um people might not understand in front of a billion users. So, but generally what we've seen is we can experiment early with the the people that really

40:46care and that's where we have like our desktop app and we have codecs and now chat work is kind of stepping into a much broader audience which we're really excited about and eventually what we want what we what we know and we think about this a lot in design is like it will tr like things will truly become like for billions of users when they don't have to like think about a switch

41:07or a mode or anything like that. And so we know that like eventually it has to kind of get distilled into that main experience. Um but it is like a really fun thing to balance and um we have to think about like people that are using this for free every day to people that are paying us hundreds of dollars and lots of different needs. It's just a

41:26matter of sort of balancing and as a designer it does add a lot of complexity for sure to think to you really have to have empathy for every sort of different type of user. Um, but this it it makes it fun for sure. >> That is such a mind-blowing point you're making about the spectrum of usage of chat GBT and CEX. I I didn't think about it that way. Like is there has there
