I believe Gary has the right idea but not the right execution. Once Tesla shows the world FSD is solved using NN, they will offer their Dojo up for training(as said on the conference call). They may even provide FSD computers for competitors as the ip itself isn't very valuable and any competent chip company can make such a chip in which NN and large memory bandwidth to feed the NN would become the main focus. Tesla will provide the entire software stack and data collection, essentially becoming AWS for car training. This is where Nvidia hope to be and why they have such a high valuation. A move like this would naturally suck valuation away from Nvidia or Intel's mobile eye into Tesla as Legacy could care less how FSD is provided, just as long as it's a package they can buy from any company and sell it to the end user with a small margin(like their entire business model).
Currently even though Tesla haven't solved FSD, Legacy auto makers have a hard time buying from Nvidia or other companies in scale due to the prohibited cost. Nvidia's L5 TRAINING platform is almost 10k, and this doesn't include the 8 or so lidars needed. Not to mention an entire cooling solution that need to dissipate about 3kw of power. Even so FSD isn't solved using this 30k-40k hardware package.
Tesla's version cost about 200 bucks which they can easily just sell it to Legacy, and then charge them a licensing fee for training for the entire life of the car. Basically FSD subscription fee for the entire auto sector.
No auto company will copy this as they wouldn't even know where to start. Nvidia, Mobile eye, and Waymo might ditch their approach asap trying to catch up, which is a totally different strategy as they mainly focused on localization using Lidar and HD maps.
This is another episode of focusing on the wrong thing. Having this FSD advantage has nothing to do with ride hailing at all. Elon Musk is not even thinking about...he's thinking about how to give everyone AI at a price.
