Self-driving cars have advanced further than AI agents in the real world not because digital tasks are technically easier, but because roads, stoplights, and traffic laws already give self-driving cars standardized scaffolding to operate within — scaffolding AI agents dropped into arbitrary digital environments don't have.
Sherwin Wu argues physical autonomy (self-driving cars) has outpaced digital autonomy (AI agents) partly because roads and traffic laws provide standardized scaffolding that AI agents, dropped into unstructured digital environments, still lack. ✦ AI generated

“Why is that the case at a technical level? Why is it that what should sound easier is actually a lot harder?”
I actually do think self-driving cars have a good amount of scaffolding in the world for them to operate in. Like not completely unlimited. You have roads, roads exist, they're pretty standardized. You have stoplights. People generally operate in pretty normal ways. And there are all these traffic laws that you can learn.

24:02remember in the early days of self-driving, a lot of the researchers around self-driving were saying that the roads themselves will have to change to accommodate self-driving. There might be sensors everywhere so that the self-driving cars can interact with it, which I think is like, retrospect overkill. But I actually do think self-driving cars have a good amount of scaffolding in the world for them to operate in. Like not completely unlimited. You have roads,
24:24roads exist, they're pretty standardized. You have stoplights. People generally operate in pretty normal ways. And there are all these traffic laws that you can learn. Whereas AI agents are just kind of dropped in the middle of nowhere, and they kind of have to feel around for them. And I actually think going off of what Olivier just said too, my hunch is some of the enterprise deployments that don't actually work out likely don't have the scaffolding or infrastructure for
24:50these agents to interact with as well. A lot of the really successful deployments that we've made, a lot of what our FDEs end up doing with some of these customers is to create almost like a platform or some type of scaffolding, connectors, organizing the data so that the models have something that they can interact with in a more standardized way. And so my sense of self-driving cars actually have had this in some degree with roads over the course of their deployment. But
25:14I actually think it's still very early in the AI agents space. And I would not be surprised if a lot of these, a lot of enterprises, a lot of companies just don't really have the scaffolding ready. So if you drop an AI agent in there, it kind of doesn't really know what to do, and its impact will be limited. And so I think once this scaffolding gets built out across some
25:30of these companies, I think the deployment will also speed up. But again, to our point earlier, I think there's no slowdown. Things are still moving very fast. That's great. Well, you know, I've thought about autonomy as a three-part structure. You've got perception. You've got the reasoning, the brain. And then you've got the scaffolding, the last mile of making things work. Maybe we can dive into the second part, which is the reasoning, which is the juice that you guys are building with
25:58GPT-5, most recently. Huge endeavor, congrats. The first time you guys have launched a full system, not a model or a set of models, but a full system. Talk about that. I mean, the full arc of that development, what was your focus? I mean, honestly, the benchmarks all seem so saturated. Like clearly it was more than just benchmarks that you were focused on. And so what is a
- ·Self-driving cars have advanced further than AI agents in the real world
- ·Digital tasks are not inherently easier than physical ones
- ·The gap is scaffolding: roads, stoplights, and traffic laws provide it
- ·AI agents in arbitrary digital environments lack this standardized structure
- ·Roads exist and are highly standardized
- ·Stoplights provide predictable signaling
- ·People generally operate in normal, learnable patterns
- ·Traffic laws offer a codified rulebook to learn from
