Typical twenty year olds don't read all the state-of-the-art papers on a subject before saying they know it all. It sounds more like he's caught up on the latest AI research and fundamentals.

If he really did read the papers then it's clear he would not say this. The papers aren't an end. They describe incremental progress. Having just returned from NIPS where most of the researchers are saying "We don't know" all the time, it is ironic.

Can you point to one such job where someone lost his/her job to "AI"?

Travel agents.

Is it really the best approach to only train from real world scenarios without any programmed constraints? Most humans are terrible drivers and there's a reason so many people die every year in car accidents. It seems like his approach might be more organic but it'd also be really hard to provide training data around emergency situations as others have mentioned here.

I'm afraid this may be also the end, more or less. From this point onwards, things get so much harder and more labor-intensive, that doing everything alone seems impossible.

I don't see why it would. Once you get enough base data you can start simulating the data from what you have, inputting different scenarios without actually encountering them IRL. Faking sensor input and randomizing should get it most of the way there.

When lives are involved handling edge cases is everything. The person stepping off a curb, the cyclist that falls in front of you, the car that weaves in its own lane and can't be used as a reference, traffic lights that are out of order, stop signs hidden by trees... and on and on. Mess one of these up while autonomous and severely injure someone and you're done.

Human drivers might only see one of these cases a month, or 6 months, but not driving over someone in that case is what is critical. Not saying it's an impossible task, but IMO it will require a lot more training data than humanly possible for one person to generate.

To be fair, this is machine learning we are talking about, not algebraic topology. The experts in ML are still proud of the fact that they figured out the chain rule...

I'd like to give him the benefit of the doubt and say that this is a comment on how smart people often accept stifling constraints on their thought and actions "because that's how it's done."

It is my belief that this self-driving car project is really a kind of first for Hotz. He's famous for finding and exploiting the error-modes in what other people built; now he's actually building something. Methinks he's about to learn a lot about himself and the nature of the world. He's clearly extremely smart, so I'm actually rather excited for him!

And yes, that happened http://www.getcruise.com/

what's with making text so thin you can't even read?

I hope the design was originally with a different image. And then the image was changed, and it wasn't redesigned.

I've thought about this a lot before actually. In my opinion, the last people with jobs will be mathematicians. If you think about everything that would be hardest to automate, I think deep mathematical theory would be the most difficult (automated theorem provers have their limits).

And chess players. Computers will never beat the best chess players.

How do you train it for emergency situations (i.e. a car suddenly turning left in front of you)? I'd imagine it would be hard to get many of those in the training data set.

Easy, you drive in a simulator! (ie: backfeed/simulate LIDAR and camera data using a video game (GTA5 for example)). Then try to simulate lots of near-crashes, reactions to traffic lights, signs, etc. Hotz's code just reacts to inputs. Simulate the inputs and you can run any training case you want.

Exactly the plan for outlier cases. Though perhaps not GTA...

Prototypical case of the 80/20 rule. He has implemented the happy case. But that system is nothing people realistically would want to drive their cars. What he did is impressive. But the results are not that outlandish for a talented person. 1) Hook up a computer to the CAN-Bus network of the car [1] and attach a bunch of sensor peripherals. 2) Drive around for some time and record everything to disk. 3) Implement so…

Why is the first comment on HN minimizing this truly impressive project? Of course it's not perfect, he's ONE person.

Yes, It's one person. WE GET IT.

This article is a hero worship piece about a guy rather than a story about the technology. It's like how you can't find an article about Theranos that isn't actually just a photo-shoot/celebrity worship article about its founder.
