“With humans, the way I almost say it in, in, in, in technical terms, it's like, there's this coupling of a context and a thread. And what I mean by that is, is like, basically each human can only operate, you know, single-threaded on, on the work that they do, and they have their set of contexts. And then there's other humans, obviously, who can do other stuff at the same time, but they have their own context, right? With agents, one of the cool things is you can have an agent that's doing multiple lines of exploration at once, but is sharing all of the context of everything that they find.”

Wu: Base model intelligence is already sufficient for autonomous software engineering
“I think that my hot take here, which I would give is I think the, I think in terms of base intelligence, we're honestly basically already there. And I think a lot of what we see actually, and what we spend our time on is less so, obviously we don't pre-train o…”
Wu: Aspiring engineers should absolutely still learn to code
“And first of all, the question of, you know, whether you should still learn the code, my answer would be absolutely yes. I think to a large extent, you know, computer science, when you take computer science classes and when you learn these fundamentals, sure, …”
Wu: 10x engineering speed will yield over 10x more code
“I think in a kind of zero sum view, you might say, well, we're gonna be 10 times faster at software engineering, and so it means that we're gonna need 10 times fewer software engineers, right? But I think in practice, what really is gonna happen is actually, w…”
