 And lots of questions about who we should be hiring. Like, do you hire the traditional machine learning PhDs? Do you hire software engineers who have never done this before? Do you hire people who are somewhere in between? And then, you know, I think for each of these decisions, we got to see the consequences of them. And then we would update. We would learn. And so I think this sort of iteration, this idea of we can't know everything in advance, but we can learn from contact with reality, I think was there in our DNA from the very beginning.
