Yeah, that's what it was
14:41
pronounced.
14:42
Internally, we don't have an A3 effort anymore.
14:47
It's Codex.
14:48
But really for me, I joined, I started building infrastructure for research.
14:54
A lot of what I did before was large-scale data storage, analysis, and then tools to understand training runs.

I did a lot of different things over my years, but it was always about building for others and making them faster and just really caring about, you know, fundamentally doing that well.

In that kinda end state, what is the, that perfect illusion for the, the typical user? Like what, what-- like if you can envision us a few years from now, what does the interaction between AI and a human look like?
17:17
Yeah, it's, um, to me, it's something that is very, very tailored to, to, to humans.

Natural language, it's like it's a human concept, right? Uh, so you know, we are used to speaking to each other, like, you know, if you write me a letter tomorrow, I'll be able to read it.
17:41
Um, you know, it's like we, we know each other quite a bit now, so, uh, you know, it's like I will be able to sort of decipher like a little bit of the emotion or, you know, maybe a little bit of the nuance behind the letter if you wrote me a letter.
17:52
Um, and all of that is, is deeply human.

How much do those resets, how much of it is a boon towards marketing and growth? Or is it, or is it just like goodwill for the developer community?
