Statements from this episode (52)
Bret Taylor: Ignored LLM progress entirely until OpenAI's DALL-E launch
“I hadn't been paying attention to large language models. I just, it didn't follow the progress after the Transformers paper. And I saw that and my reaction was, I had no idea computers could do that.”
Bret Taylor: Most acquired founders fail to make the necessary identity shift
“What I've observed is it's that identity shift is a prerequisite for most of the other things. It's not simply your ability to handle the politics and bureaucracy of a bigger company or to navigate a new structure. I actually think most founders don't make tha…”
Taylor: 80% of acquirers and acquired teams disagree on success metrics
“If you went to most of the, like, larger acquisitions in the Valley, and you, two weeks after it was closed, interviewed the management team of the acquiring company and the acquired company, and you asked them, like, what does success look like two years from…”
Taylor: Acquired Founders Do Not Take Enough Accountability for Post-Merger Success
“And I think founders don't take on enough accountability towards making these acquisitions successful as I think they should.”
Taylor: Tough M&A talks should happen between term sheet and close
“I think it's right after that. So where people have really committed to the key things, how much value, why are we doing this, the big stuff. And there's usually you know, many, lots of lawyers being paid lots of money to turn those term sheets into, you know …”
Bret Taylor: Great company cultures empower founders to fix small details directly
“I believe in cultures where, you know, founders have license to go in and all the way to a small decision and fix it. The infamous question mark emails from Jeff Bezos, you know, that type of thing. That's the right way to run a company.”
Bret Taylor: Engineers Who Refuse to Evolve Beyond Technical Roles Plateau
“I think engineers who are unwilling to Elevate their identity from what they were to what it needs to be in the moment often leads to sort of plateaus in companies growth.”
Taylor: Server outage root-cause analysis is effective for diagnosing lost sales deals
“Everything from process, like how engineers do a root cause analysis of an outage on a server is a really great way to analyze why you lost a sales deal.”
Taylor: Over-applying engineering mindset leads to analysis paralysis in human problems
“And so I would say, I think a lot of things coming with an engineer mindset could really benefit, but I do think that taking that to its like logical extreme can lead to analysis paralysis, can lead to over intellectualizing some things that are fundamentally …”
Taylor: The craft of software engineering will be completely different by 2027
“And if I look at the actual craft of software engineering that we're doing right now I think it's literally a fact that it'll be completely different two years from now.”
Taylor: Sierra charges strictly for outcomes rather than software license fees
“Rather than having our customers pay a license for the privilege of using our platform, we only charge our customers for the outcomes.
meaning if the AI agent they've built for their customers solves the problem, there's like a, usually a pre-negotiated rate…”
Taylor: Every engineer at Sierra uses Cursor for code generation
“Every single engineer at CIRA uses a cursor, which is a great product that Basically integrates with the IDE, Visual Studio Code, to help you generate code more quickly.”
Taylor: Generating AI code in human-designed programming languages is a local maximum
“It feels like a local maximum in a really obvious way to me, which is you have a bunch of code written by people written in programming languages that were designed to make it easy for people to tell a computer what to do.”
Taylor: Treating software engineers as machine operators will make development more robust
“I have a strong suspicion that if we designed these systems with the role of a software engineer in mind being an operator of a machine rather than the author of the code, we could make the process Much more robust and much more productive.”
Taylor: AI can recursively solve most problems in AI development
“I do think it can be turtles all the way down. You can use AI to solve most problems in AI.”
Taylor: AI marks a software shift as significant as the GUI
“I think we should recognize that we're in this brand new era as significant as the GUI. You know, it's like a completely new era of software development.”
Taylor: AGI means matching human capability on any computer task
“I think a reasonable definition of AGI might be that Any task that a person can do at a computer that system can do on par or better.”
Taylor: Superintelligent AI will not accelerate all industries equally
“The progress in that domain isn't necessarily limited by intelligence but by other social artifacts. So as an example, and I'm not an expert in this area, but if you think about the pharmaceutical industry, my understanding is, you know, the, one of the main b…”
Taylor: Reasoning models generate net new ideas, breaking the data wall
“What's really interesting about, you know, reasoning and reasoning models is I think I feel really optimistic these models are generating net new ideas, and so it really affords the opportunity to break through some of these, the data wall as well.”
Taylor: OpenAI o1 used reinforcement learning on chains of thought
“What at OpenAI, what we did with the O-one model, which is to do some reinforcement learning those chains of thought to really reach new levels of intelligence.”
Taylor: AGI progress is very unlikely to stall across all key inputs
“The idea that we will be stuck on all three of those domains feels very unlikely to me, and in fact, what we've seen because of the potential economic benefits of AGIs, we're in fact seeing breakthroughs in all three of them”
Taylor: Engineers Remain Accountable for AI Safety Regardless of Autonomy
“At the end of the day, we are accountable for the safety of the systems we produce. Not just OpenAI, like every, every engineer and that's a principle that should not change.”
Taylor: Pre-training a fourth-best foundation model offers highly questionable ROI
“If you're pre-training a foundation model that's the fourth best that's gonna cost you a lot of money, and the return on that investment is, is probably fairly questionable, because why use your fourth best large language model versus a frontier model or an op…”
Taylor: AI model market will consolidate into a few massive capex players
“I think we have probably have too many people building models right now. There's already been some consolidation actually of companies being folded into Amazon and Microsoft and others. But I do think it will play out a bit like the cloud infrastructure busine…”
Taylor: Pre-training startups have pharma-like costs without the pharma business model
“I would have a hard time personally, like, funding a startup that says, I'm gonna do pre-training, you know, it's, ah, it's, I don't really know, like, what's your differentiation in this marketplace, and I think a lot of those companies you're already seeing,…”
Taylor: GPT-4o Mini is likely cheaper than self-hosting open-source models
“I haven't done the math on it, but it's probably cheaper to use that than to host, self-host any of the open source models.”
Taylor: AI model adoption will mirror cloud computing trade-offs
“And I actually think of it as, you know, just like in cloud computing, you'll end up with a price performance quality trade off and for any given engineering talents, they'll have a different answer and that's appropriate.”
Sierra founders use OpenAI o1 Pro to critique company strategy
“Clay and I use the O-one pro mode for, like, criticizing our strategy at CIRA all the time.”
Taylor: ChatGPT will be the primary delivery mechanism for AGI
“Is I do think that, It will be the delivery mechanism for AGI when it's produced, and not just because of the many researchers at OpenAI, but because of the amazing, like, utility it's become from individuals.”
Bret Taylor uses GPT-4o to refine prompts for slower reasoning models
“I often, with the reasoning models, which are slower, will use a faster model first, GBT-IV-O, to refine my prompts.”
Taylor: AI research labs will naturally go wherever compute is built
“But in general, where there is compute, the research labs will find you know, and so I think that's it.”
Parrish: El Salvador replaced public teachers with Synthesis AI tutoring software
“Oh, so they developed this Synthesis, this AI company developed this tutor, which actually teaches kids, and it's so good that El Salvador, the country, just recently adopted and replaced their teachers.”
Taylor: Raw coding speed is no longer a differentiated engineering skill
“You know, if you define your role as a software engineer is how quickly you type into your IDE, the next few years might leave you behind, you know, because that that is no longer a differentiated, you know, part of the software engineering experience or will …”
Taylor: Nothing is stopping AI from mastering mathematics
“There's not really anything keeping AI from getting really good at math. There's not really an interface to the real world. You don't need to do a clinical trial to verify something's correct.”
Taylor: AI will shift intellectual power from deep specialists to cross-domain generalists
“I have a completely personal theory that it will benefit deep generalists in a lot of ways, too, because your ability to understand a fair amount in a lot of domains, and leveraging AI knowing where to prompt the AI to go explore and bringing together those do…”
Taylor: Software Value Lies in Closed-Loop AI Systems, Not Chat Interfaces
“What I'm excited about in the software industry is not necessarily a large language model with a prompt and a response being
The product of AI, but actually end to end closed loose systems that use large language models as pieces of infrastructure.
And I actua…”
Taylor: Speculatively patenting generated ideas is value destructive
“I think patents make sense if it's protecting something that's an active use that you know, invented, and you're trying to you know, like the standard, you know legal rationale for patents, just generating a bunch of ideas and patenting, it seems Destructive t…”
Taylor: Google Maps Would Have Been Far Less Interactive Without Desktop Precursor
“And I think that by having the goalposts so far down the field, because they had just started with this Windows app, which was sort of a quirk of Lars and Jens, just like technical choices, we made much bolder technical bets than we would have otherwise. I thi…”
Taylor: Google Maps rewrite reduced bundle size from 200 KB to 20 KB
“We went from a Bundle size of 200 K to a bundle size of 20 K and it was a lot faster and better.”
Taylor: Self-driving software will likely shift to monolithic models replacing heuristics
“A lot of smart people think that eventually it'll probably be a more monolithic model that encodes many of the same rules. You have to throw out a lot of code in that transition, but it doesn't mean it's not the right thing to do.”
Taylor: AI disproportionately benefits sectors where intelligence limits growth
“AI will probably benefit different parts of the economy disproportionately. There will be some parts of the economy that can essentially Where intelligence is a limiting factor to its growth and where you can absorb almost arbitrary levels of intelligence and …”
Taylor: Nvidia may not be a 20-year AI bet as infrastructure shifts
“Nvidia will probably benefit from all of the investments in AI. I'm not sure I would do that over a 20 year period, just assuming that the infrastructure will shift.”
Taylor: Technology and finance will probably benefit most from AI
“Two that are, I think, probably going to benefit a lot are technology and finance you know, where you're, You know, if you can make better financial decisions than competitors, you'll generate outsized returns, and that's why over the past, you know, 30 years,…”
Taylor: Software engineering supply is not close to being solved by AI
“At some point, we will be we will no longer be supply constrained in software, but we're not anywhere close to it right now, and you're taking something that has always been the scarce resource, which is software engineers, and you're making it not scarce, and…”
Taylor: AI agents will rapidly erode legacy seat-based software pricing models
“AI, I think, will change the landscape of software to be tools of productivity that, to agents that actually accomplish tasks, and I think it will Help some companies who, for whom that's a amplifies their existing value proposition and it will really hurt oth…”
Bret Taylor: Most people will use one or two personal AI agents daily
“One is personal agents, so I do think that most people will have Probably one, but maybe a couple AI agents that they use on a daily basis that are essentially amplifying themselves as an individual.”
Bret Taylor: Personal AI agents will take a while to become robust
“I think it might be a really hard product to build because when you think about all the different services and people you interact with every day, it's kind of everything. So it's not, it has to generalize a lot to be useful to you. And because of the Personal…”
Bret Taylor: Constraining agent autonomy creates commercially viable products today
“By narrowing the domain of autonomy, you can have more robust guardrails and even with current models actually achieve something that's effective enough to be commercially viable today.”
Taylor: AI agents fundamentally invert UX by handing agency directly to customers
“If you think about a modern website or mobile app it's essentially, you've created a directory of functionality from which you can choose. But the main person with agency in that is the creator of the website. Like, what are the universe of options that you ca…”
Taylor: Bureaucracy accumulates when companies add well-intentioned processes after every error
“The root of bureaucracy is often when something goes wrong, companies introduce a process to fix it. And over those, like sequence of 30 years, the layered sum of all of those processes that were all created for good reason with good intentions end up being a …”
Taylor: Bureaucracy and inaccurate internal storytelling cause companies to die
“The combination of, Bureaucracy and inaccurate storytelling I think is the reason why companies sort of die”
Taylor: Removing bureaucracy requires top-down leadership because managers lack incentives to cut process
“Often mid-level managers don't get credit for removing process. They often are held accountable for things going wrong and I think it really takes top-down leadership to you know, remove bureaucracy”
