A company's edge comes from discovering valuable unknown truths, because knowing what others do not is what lets you do what others cannot.
if you are good at finding valuable unknown truths then it means you're going to know a lot of things other people don't know. And if you know a lot of things that other people don't know it means you can do a lot of…

The specific rules taught as clean code are simply bad programming practices, and they get worse when you apply them together.
If you look at those things, they're kind of just bad programming practices. I I don't really know how else to say them. They don't mesh well when you put them together.

You do not have to know how it works underneath, but depth is where invention comes from — nobody who only knows the surface invents a programming language.
But if you ever want to get better at anything, and sometimes that depth, that nuance is the thing that leads to an invention, right? If you know how a compiler works, if you know how memory management works, that might…

Overly prescriptive instructions make a coding agent worse, for the same reason a micromanaging boss makes a programmer worse.
it was actually being damaged by overly prescriptive humans. And any programmer who's had a pointy-haired boss knows exactly what that is like. When the boss walks into the room, doesn't know anything, starts telling…

If you are not going to read the generated code, what you need is conformance testing: proof that it performs within the boundaries of the code it replaced.
Okay, if I'm not going to read this code, how do I know it's going to perform within boundaries of the last code that I generated? That is conformance testing.

Flow is not required to perform at your best: a clutch state, in which you perform well and it still feels like hard work, is just as legitimate a peak state.
And both of those are perfectly reasonable states in which to perform. And assuming that you have to be in flow to perform just isn't true if you look at like how you know athletes perform in the moment.

Knowing both the deep history of a field and its bleeding edge is what makes someone genuinely differentiated in it.

Locality is what makes a language good for AI: if a single file states what it imports and what it offers, a model never has to hold the whole program at once.
but but if you have good locality where you you clearly stating what you're importing and whatever and and you can analyze just a single source file and from that extract its protocol to the outside world without having…

Opening school to everybody necessarily made average measured performance look worse, because the students who used to be excluded are now in the data.

A robot needs far less memory than it seems, because Moravec's paradox says the cognitively demanding tasks are the ones that need context, not the physical ones.
But the reason why it's not the most important thing for the kind of skills that you saw when you visited us, it at some level I think it comes back to Moravik's paradox. So Morovik's paradox is basically that it's like…

The overhead of learning a new programming language no longer justifies sticking to the two you know: start writing in a third now, without learning it first.

Anyone outside a frontier lab will find their judgment about AI drifting, because the systems are opaque and what is coming is not visible from outside.
