#446 – Ed Barnhart: Maya, Aztec, Inca, and Lost Civilizations of South America

To be clear, I think they sort of understand code really well. While they're being pre-trained, the representation that's being built up, almost certainly somewhere in the stream, the model knows that maybe there's something sketchy going on. It sort of has some sketchiness, but actually eliciting the sketchiness to...

#446 – Ed Barnhart: Maya, Aztec, Inca, and Lost Civilizations of South America

Part of it is that humans are really calibrated on which bugs are really important. It's not just actually saying there's something sketchy. It's like, is this sketchy trivial? Is this sketchy like you're going to take the server down? Part of it is maybe the cultural knowledge of... Like, why is a staff engineer a staff engineer?

A staff engineer is good because they know that three years ago, like, someone wrote a really, you know, sketchy piece of code that took the server down. And as opposed to, like... As opposed to maybe just, like, you know, you just... this thing is like an experiment. So like a few bugs are fine. Like you're just trying to experiment and get the feel of the thing.

And so if the model gets really annoying when you're writing an experiment, that's really bad. But if you're writing something for super production, you're like writing a database, right? You're writing code in Postgres or Linux or whatever. Like your Linus Torvalds, it's sort of unacceptable to have even an edge case. And just having the calibration of like,

In fact, I actually think this is one of the things I learned from Arvid is, you know, sort of aesthetically, I don't like it. But I think there's certainly something where, like, it's useful for the models. And humans just forget a lot. And it's really easy to make a small mistake and cause, like,

You know, my hope initially is, and I can let Michael chime in too, but it was like, there's, It should, you know, first help with the stupid bugs. Like, it should very quickly catch the stupid bugs. Like, off-by-one errors, like, sometimes you write something in a comment and do it the other way. It's, like, very common. Like, I do this.
