The fact is Tesla's all vision system has already resulted in 2 decapitations and many fatal accidents.

Moot point. Still less accidents than with human drivers in average. Not to say those were negligent drivers abusing the system. Nothing will be 100% perfect ever, and Tesla makes the safest cars you can currently buy. Basically all naysayers like to call upon anecdotal evidence and avoid hard statistics.
One death in Tesla somewhere in China - big news. 100 people die in car crashes in US every day - who cares.

The fact is Tesla's all vision system has already resulted in 2 decapitations and many fatal accidents. The only saving grace they have now is they get to pass the blame to drivers. "Should have been paying attention, should have managed it themselves". They won't have that to fall back on if they call it FSD. I guess we'll see what happens in the future. Just don't forget to question them when they say they are the experts and their demo is no more impressive than a years old Google demo.

So, I think you need to be a little bit realistic as far as the safety incidents go -- I mean it will never be zero, or at least not for a long time. It will however be much better than a human driver and that's an improvement we will see right away. All of this same sentiment will apply to any other manufacturer, too.

As far as what Tesla is doing that nobody else is ... you have to talk about that ASIC. I don't know if anyone else is building a fully custom ASIC for this purpose, but but I can't imagine that very many if anyone else is. The ASIC is extremely efficient, although not that fast ultimately. It has 2 neural network processors that do 36TOPs apice in each chip, for a total of 72TOPs per chip. For example the TU102 chip used in the GTX 2080 Ti can do 228 TOPs. However TU102 does that with 754mm^2, 18.6B transistors, and 250W. The Tesla ASIC is only 260mm^2, 6B transistors, and like 30W. That Tesla ASIC also has 12 fairly large ARM cores AND an entire GPU on that same die as well.

(All TOP numbers are for INT8)

Those figures are completely incomparable FWIW.

How so, they are FMA dot products, just like the tesla chip is doing. Smaller matrices, though, but I don't believe that makes them not comparable as those numbers are including each add and each multiply for each position in the matrix. (16x16 vs 96x96)

By the end of Last year Musk was supposed to release space tourism. I am still looking for a space tickets sales office. The problem is this idiot smokes too much.
