If this is true, why do Waymo (or any of the top 10 self-driving companies besides Tesla) use Lidar? Two facts: 1. Tesla can't use Lidar because of cost and aesthetics. 2. Elon has a strong incentive to oversell their approach to self-driving.

From the presentation they mention that Lidar is good at developing tech demos quickly, but they've found it is insufficient in reality. Which of those 10 companies you reference have moved far beyond tech demos?

I think the point was that lidar is too low resolution. You must have very high resolution (in both time and space) to achieve L4 or L5; to accurately determine if a pedestrian is not paying attention, or if a bicyclist is looking to cross the road. Not that Tesla is doing any of that right now, they most likely are not. But a lidar is not going to, either. Not ever, which is the point. I thought the fleet learning a…

Musk would have you think it's a Lidar vs. cameras debate. It's not. It's a Lidar + cameras vs. just cameras debate. Lidar has significant shortcomings. So do cameras. But together they make for a decent perception system. With regards to fleet learning, Tesla has been going on about it for years, but more data is not better. Better data is better. Clifornia's disengagement reports have seen criticism because they pl…

Elon Musk is noted for his premature optimization. Case in point: both the Gigafactory (vastly overbuilt for the quantity of batteries actually produced) and the Alien Dreadnought (vastly overbuilt for the number of cars Tesla current produces...assuming that Tesla is ever able to get the fancy automation working). Boring Co digging a two-mile tunnel in West LA without bothering to learn how to pour concrete smoothly…

It's easier to optimize a working system than it is to get an optimized system working.

What kind of event is this and who is it targeted to? Right now there’s a comparison of energy consumption for different instructions on processors, I’m very confused.

Surprisingly technical versus what I'd expected, but it is targeted specifically at investors.

Karpathy's presentation is really good. Watch it later if you get some time. The key points are - Telsa is using fleet for learning (Fleet learning). This has 3 components, a. Trigger infrasture that collects the kind of data telsa is looking for training. The rational here is we don't need massive amounts of same kind of data but needs right kind of data for training neural networks correctly. b. Data Engine which l…

>"People drive vision only." Can you elaborate on what you mean here? Do you mean that Tesla will only be using Computer Vision for autonomy? Doesn't or wouldn't Lidar compliment CV? Or is there a practical design consideration that makes them mutual exclusive?
