 And we just figured, well, hey, if a Tesla can do it on the highway, why can't we do it for people on the sidewalk? And then we started building a hacky wearable device with lots of wires sticking out of it, a camera. But we quickly realized if we want to make it affordable and scalable so that it works for everyone, we need to be able to optimize the AI so that it runs locally on the phone that they already own. And so the moment that we were able to do that, we quit our jobs and started full time.
