1 supported 0 partly supported 0 contradicted 1 not yet assessed 9 not checkable as stated how the 11 claims stand · each chip opens the sources
5 predictions · 6 assertions · 2 opinions · 7 insights · 4 disclosures · every statement was checked. The predictions and assertions are the 11 claims: statements the public record can support or contradict. 1 is resolved, 1 is not yet assessed, and 9 name no date, number or outcome precise enough to check. Everything else (opinions, insights, what ifs, disclosures) can never be settled by the record, so it carries no assessment.
The record, in short
What the tape says about how Sherwin argues and how the claims held up. Everything they said, and everything said about them, is in the tabs below.
Expressed certainty vs assessment result
weighted support: a fully supported claim counts one, a partly supported claim counts half. Each filled bar is clickable and opens exactly those claims; "none yet" means nothing said at that certainty level has resolved yet
How they sound: not measured why? →
We measure speaking style by listening to the audio itself, and a fair number needs at least 2,000 words from one person on tape we have measured. There is too little of Sherwin Wu on measured tape to publish a rate. This says nothing about how they speak.

Wu: Blindly following customer requests leads to AI product local maxima
“Because the field is changing so much at any point in time, you know, a lot of people are kind of in this local, local maximum. And if you just blindly listen to your customers, they'll, they'll be like, yeah, I want a better vector store. Like I want a better…”
Wu: OpenAI engineers using Codex open 70% more PRs
“So they're actually opening 70% more PRs and than the engineers who aren't using Codex as much and the gap is widening.”
Wu: AI tools widen the productivity spread across engineering teams
“Codex really empowers, like, top performers to get a lot, like, to be a lot more productive, and so it really, like, and I think this may be true for AI more broadly, like, across society, which is, like, the people who really lean in, or, like, the people who…”
Wu: AI will enable engineering managers to manage far more than 6-8 engineers
“My sense is I think managers will be able to manage much larger teams in this world. Kind of like how, you know, like software engineers are managing 20 to 30 codexes. My sense of these tools will allow managers, people manage to be higher leverage and will al…”
Wu: A one-person billion-dollar startup will likely exist eventually
“It's like, yeah, if, you know, if people are so high leverage, at some point there will likely be a one person billion dollar startup.”
Wu: Rise of AI micro-companies could shrink venture-scale return opportunities
“You know, it might, we might end up in in a world where there's just, like, a handful of big players that are offering platforms and supporting all of these startups, but, you know, the types of venture-scale return startups that can really hundred or thousand…”
Wu: AI startups should build for capabilities that are 80% viable
“My general advice, and I've been giving this to people for a while, and I think it's still true today, is make sure you're building for where the models are going and not where they are today. You know, the, it's clearly a moving target, and I think a lot of t…”
Wu: 95% of OpenAI engineers use Codex and 100% of PRs are AI-reviewed
“So, 95% of engineers use Codex.
100% of our PRs are reviewed by Codex daily as well, so basically any code that goes into production that's merged in, Codex kind of has its eyes on and suggests improvements, suggests changes in the PRs.”
Wu: OpenAI engineers juggle up to 20 parallel Codex threads simultaneously
“I know many of the engineers on my team basically have like, 10 to 20 threads kind of being pulled on at the same time. Obviously not active running codex jobs. But just a lot of parallel threads. They're checking in on what they're doing. They're steering the…”
Wu: OpenAI team is maintaining a 100% Codex-written codebase without manual coding
“So there's a team that that's actually doing an experiment right now with an open AI where they are basically maintaining a 100% code expert and code base. So, you know, like, you know some, you know, you'll have the AI write code, but you'll obviously end up …”
Wu: Codex cuts OpenAI code review times from 15 to 3 minutes
“And it makes, you know, code reviews go from a, you know, I don't know, 10:15 minute task to sometimes even just like a two to three minute task, because you have a bunch of suggestions already, already baked in.”
Wu: The vast majority of code at OpenAI is authored by AI
“Almost every engineer heavily uses Codex in all of their tasks at this point, and so I, you know, if I were to guesstimate, like, the vast majority of code at this point is, It was probably authored by AI.”
Wu: OpenAI managers use internal ChatGPT for employee performance reviews
“We're doing performance reviews right now, and it's actually really easy to use ChatGPT with internal knowledge, hooked up to GitHub and like our Notion docs and Google docs. To give a, get a really good sense of what this person has done over the last 12, 12 …”
Wu: Organizational barriers are the main bottleneck to AI-assisted shipping
“If people are just like cranking PR after PR, the main thing bottlenecking progress and, you know, shipping something tends to be organizational or like process oriented.”
Wu: AI models could execute multi-hour to day-long tasks in 12-18 months
“If you follow this trend, like, I think, like, in the next 12 to 18 months, we could see models that could do multi-hour long tasks very, very coherently. At some point, it might reach, like, you know, six hours a day long task.”
Wu: Native speech-to-speech multimodal models will improve dramatically in 6-12 months
“I think they're gonna get a lot better at audio over the next six to 12 months, especially the likes, you know, the native multimodal models, the speech-to-speech ones.”
Wu: AI startups fail from lack of customer resonance, not OpenAI competition
“Every startup that I've seen that is kind of fizzled out is not because open AI or, you know, big lab or Google or something has come to squash them. It's because they built something and it like really didn't resonate with the customers.”
Wu: Every model released in OpenAI products is released in the API
“Every single model we've released in one of our products gets released in the API.”
Wu: OpenAI engineering managers write all their code using Codex
“And so I know for myself and some of the other EMs,
Engineering managers at OpenAI.
all of our code is written by Codex at this point.”
Wu: Coding agent failures are usually caused by missing context or underspecification
“A lot of the time when the coding agent is not doing what you want, it's usually a problem with context and just, like, information that you've given it. It's just either underspecified or there's just not enough information around how to do something availabl…”
Wu: Tech-adjacent non-engineers drive the most enthusiasm for enterprise AI adoption
“The pattern I've seen is it tends to be these like software engineering adjacent, like basically technical people, but are not software engineers. I think those are the ones who get tend to get most excited around this. It's like, you know, maybe the, it's lik…”
Wu: Enterprise audio AI is hugely underrated compared to text coding tools
“Audio, especially in the enterprise and in a business setting, I think is a hugely underrated domain still. Like, everyone talks about coding. It's all text. But we're talking in audio. A lot of the world's business is done via audio. A lot of services and ope…”
Sherwin Wu: AI business process automation is massively underrated in Silicon Valley
“And so I'm just extremely bullish on this general category of, like, And I think it's underrated because it's so different from what we think about in Silicon Valley, people tend to not think about it. But how can we apply AI and some of the tools and framewor…”
