The complexity of the thing is so crazy that it exceeds, it's going to exceed our ability to program and until robots can do the programming for these AVs, we're not going to actually get to that. It really bothers me. One of the things that bothers me most about Elon Musk is that to come back to Elon. That I have is that they're going to get them 95% of the way to towards working and being safe. And then the rest of us are going to have to fill in the other 5% by trying to figure out how the algorithms work.
