The benefit they point out is 200fps vs. 2000fps, but is that actually that useful? In the post of OpenAO's robot, they said that improving the response times gave no significant gains. Only thing I can imagine would be allowances for wider and deeper neural nets.

More data points can't hurt right? Maybe this is part of their push to move away from third party suppliers?

“Nvidia’s hardware was handling about 200 frames per second, its specialized chip is able to do crunch out 2000 frames per second “with full redundancy and failover”.”

What are the real-world benefits going from 200 to 2000 frames a second? 200 seems quite fast.

This is pretty bad from a hardware/software verification perspective. People who care about correctness can just go home, I guess. It's amazing that we're gonna let these things on the streets. When you weigh almost 2 tons and can go >100mph, it doesn't matter if you have a gun mounted on you or not, you are a weapon .

Yeah because all the verified neural networks made from meat travelling >100mph are legit ok to drive 100% of the time. There are no road accident deaths to speak of.

What do you mean by correctness in this context?

So much for no new hardware required for L5

Just wait until they admit that they need LIDAR too... Cha Ching! Various Autopilot accidents strongly imply that whatever the computer “brain” is doing doesn’t matter if it doesn’t have sufficient “eyes” to actually see things like a fire truck, cop car, or bollard.

And yet squishy meatbags manage to sensor fuse a stereoscopic image (plus nascient sound based imaging) into a reliably rendered picture of the world...

does correctness even work with deep neural networks to begin with? especially with the existence of adversarial examples, out of domain situations, etc

Adversarial examples are a thing even for humans, and yet here we are.

Earlier quoted context omitted.

Does it matter if Tesla does the hardware swap on existing vehicles for free? Costs should not be high to do so if it’s their own silicon and the swap is done as part of regular maintenance at Tesla service centers. The benefit of high margins and sophisticated engineering is you can get away with a lot of unknowns and promises.

Yes. It demonstrates that their claims have been complete BS.

You don’t have to be 100% right to be profitable and have loyal customers (clearly).

Our eyes are incredibly advanced compared to any camera in existence, and hooked up to a real life AGI, and we still fuck up. No comparison. We meatbags are still far more sophisticated and battle tested than anything said meatbags managed to build, which is why so much of our building attempts to replicate our own capabilities.

They seem to have a rather low number of mistakes per billion miles,* so I don't know if more sensors are actually required. I suspect the larger issue is "To Err is Human; To Really Foul Things Up Requires a Computer" https://quoteinvestigator.com/2010/12/07/foul-computer/

The current model makes assumptions that sometimes turn out to be false. So yea it's not going to get to perfection, but level five only needs better than human not perfection.

* Granted I am likely a bad driver, but I don't think I could do this well.
