Statements from this episode (26)
Nadella: System software is entering a golden age of infrastructure opportunity
“It's golden age of system software. Quite frankly you know, today, if I had to think about anybody who's building at the infrastructure layer, not just the hyperscalers, but even the startups, I think that's a tremendous opportunity.”
Nadella: The ultimate benchmark for AI is creating broad economic surplus
“It's for one thing and one thing alone, which is to drive ultimately economic growth and GDP growth. So if I had to ask me my benchmark for AI is, is it creating surplus in the world around us? One community, one country, one industry, one company at a time.”
Nadella: AI foundation models are the modern equivalent of SQL engines
“So I think it's still possible for anyone to build an app tier on top of a model, and you have to sort of abstract yourself and say, yeah, the model is just like SQL was to me. And so I think that, I mean, I always dreamt of a moment when AI slash machine lear…”
Nadella: AI product creation will center on data feedback loops for post-training
“But the interesting thing is the feedback loop, the data path inside the product that then is used in order to post train, in order to be able to do the right tool you know, selection that seems to be the place where product creation is all gonna happen.”
Nadella: AI energy consumption requires social permission and real economic surplus
“If there's one lesson history has taught us is that if you're going to use energy, you better have social permission to use energy. So that means you've got to make sure that the output of this AI is socially useful. In other words, if we really are not creati…”
Nadella: AI will create measurable value in healthcare, education, and productivity within five years
“I think the real question in the next five years is we've got to produce enough products that are creating great value, which I'm very confident of, right, by the way, in healthcare and education, in, Ah, in productivity. So there's many, many domains, but tha…”
Nadella: LLM-powered EMR discharge workflows will easily pay for themselves
“And so if you really take something like a simple thing like discharge the amount that you take the back end of an EMR system with just an LLM and a prompt that itself is going to save so much time and money and energy that it would sort of pay for itself.”
Nadella: Change management is the real rate limiter for AI deployment
“So that change management is the real rate remitter, right? Because you're now taking the means of production in an insurance company, in a financial services company, in a healthcare company, in a software company. And saying, we are going to change everythin…”
Nadella: LinkedIn merged design, engineering, and product into full stack builders
“Like, you know, at LinkedIn, I think they took multiple of these functions the design function, the front end engineer function, the product function, put them all together and said, we're going to have full stack builders.”
Nadella: Palantir's forward deployed engineer model is fantastic for AI adoption
“That's like the exciting thing is the Palantir model, which I think is a fantastic model. And why is that? That is because of that change management. Because I think you really need to help customers, partners really understand the benefits of any product you'…”
Nadella: Reasoning models paired with human synthesis are the true frontier
“Now, like having a sophisticated reasoning model and your prefrontal cortex work together whereas a lot of the mundane Stuff is getting done by even some core agent or what have you. That I think is definitely the frontier.”
Nadella: Inference-time compute adds another massive AI scaling law
“Then this inference time compute seems to have really added in another massive scaling law.”
Nadella: AI labs will shift toward integrated reasoning models within a year
“What is the pre-training to RL the end-to-end training loop that's the next, you know, big sample? That I think is also what I think will happen in the next year. So I would say, if that is another scaling law breakthrough, because we will be, like, if you sor…”
Nadella: "Artificial intelligence" is a misnomer and AI should not be anthropomorphized
“To me, this artificial intelligence is unfortunately the worst name we could have ever picked And so I'm not into this anthropomorphizing AI at all. I mean, I think of it more. I come at it as it's a tool. It's not trying to replicate how we think.”
Nadella: Sophisticated AI applications require memory, tool use, and entitlements scaffolding
“If I look at the next frontier, I would say there are three things, right? One is memory the other one is tools used, and then the third, which I think is perhaps the most important thing, is entitlements which is basically, if I'm gonna take action, what enti…”
Tan: Y Combinator will continue to fund a ton of SaaS
“A lot of us in this room, you know, YC will actually fund a ton of SAS and we'll continue to do so.”
Nadella: Just-in-time generated and packaged software will coexist
“So I think, yes, you can generate applications just in time. You could have a prefab application that is really helping with the feedback loop to the model, and I think both of these things will exist together.”
Nadella: Software engineers will become architects as everyone builds software
“What I think will happen is all of us are going to be creating software, but there is going to be a job called a software engineer. It's going to be different, but I look at it, right? You are really taking a software engineer and saying you're now a software …”
Nadella: Legal liability guarantees humans will remain in the AI loop
“Because one thing that we don't talk about is the legal liability, by the way, until some real laws change, are going to be with humans and institutions humans build. And as long as that is true, we're gonna have to really make sure the human is in the loop, a…”
Nadella: AI model capability is overhyped relative to real-world impact
“That is the under-hyped story, I think. Because right now the over-hyped thing is the model capability, and the model capability is fantastic, but man, if we can somehow get the world to recognize that this is making a real difference in the lives of people ev…”
Nadella: World Bank study found AI copilots are top education tech intervention
“By the way, one of the other ones, since you brought it up, there was a World Bank study they did, I think in Nigeria, and now they've taken it to Peru or Chile, one of those in South America. It's, you know, we've been working at Microsoft forever on can ther…”
Nadella: Vision plus speech AI represents a transformative browser moment
“The two things that are just pretty surreal to me is kind of like a new browser moment, right? There is both vision and speech. I leave it on all the time. It can see what I see, and I can speak to it. That seems like a precision mouse movement, right, to me, …”
Nadella: AI agents doing computer use for humans is the direction of travel
“Yeah, I mean, I think that has been the dream, which is, can these agents Become your computers. And they do the computer use for you. And that absolutely, I think is the direction of travel.”
Nadella: Microsoft achieved physics breakthrough to fabricate Majorana quantum chip
“Finally we've had a physics breakthrough, and we were able to actually fabricate that particle, and so therefore that's what has led to this chip.”
Nadella: Quantum computers simulate nature, while AI acts as an emulator
“If you want to understand the language of nature, which is simulation I think the best way to do it is through a quantum computer, because after all you know, Physics and nature is quantum. And so therefore, but AI is, I think of it as an emulator of that simu…”
