It seems to make sense to put a leading computer vision guy in charge of a leading computer vision project. As smart as Lattner is, the hardcore bleeding edge of computer vision and driving AI must be out of his comfort zone, given his background.
The downside for us is that, on complex software projects like Autopilot, you don't just change the guy in charge then see magical results a week later.
Andrej must be bursting at the seams with ideas for this - it sounds like his dream project. But, it'll still be a few months down the line before we start to see any of his touches in the software, at least. I'm looking forward to what he can bring - seems like he's exactly the right guy to give AP that leap forward and inspire the rest of the team.
All the best to Chris - I'm sure he did a great job whilst at Tesla, and will be snapped up quickly!
