I don't know what's going to happen with this project of his, but this certainly is an interesting article: >Sitting cross-legged on a dirty, formerly cream-colored couch in his garage, Hotz philosophizes about AI and the advancement of humanity. “Slavery did not end because everyone became moral,” he says. “The reason slavery ended is because we had an industrial revolution that made man’s muscles obsolete. For the…

Regarding slavery that's a fatalistic attitude that's not very good for the advancement of human societies. The other side of the coin of his "technology outgrew slavery, and thus we got rid of it", is that if tomorrow's technology demands some moral monstrosity, to "work better", we can't but bend over and accept it. Neither human struggles (from the civil war to MLK and Rosa Parks), nor desires and leadership come…

re >slavery ended is because we had an industrial revolution that made man’s muscles obsolete

I think that's basically wrong also. It fits better with the advent of the printing press than the steam engine.

Well, he didn't actually build the car. He built a system that operates the existing car's steering and speed controls. And comparing the proper software solution to a CRUD app undermines the work that's been done by the big players in the space for the past several years.

Well yes, he only built the software that operates a car without a person driving it, connected it to a car, and did it all by himself . One person. My point was that what 99% of HackerNews does is likely nowhere near as interesting or as difficult, so when the top comments are all shitting on someone who did something that's actually pretty amazing, HackerNews can go to hell. I mean that from the bottom of my heart.…

What he did was extremely impressive. But he's up against really high expectations. People expect him to have made massive breakthroughs in self driving car technology. Against that expectation, it doesn't seem so impressive.

He must have rich patents or a sponsor. The Lidar isn't cheap (50k).

$8k - http://velodynelidar.com/vlp-16.html

It looked like the VLP-32. The VLP-16 is pretty new, I am surprised it's already available, last time I checked it wasn't. Google cars use the VLP-64 which costs 70+k.

Doesn't it seem possible that we could start testing the cars in a simulated environment?

Simulated environments aren't accurate enough (inputs are too clean, other drivers don't act real, etc) and would end up training the software to do the wrong things. A more reasonable approach would be to record the activities of multiple safe human drivers across a wide range of situations and then train the software to act like them.

He said for testing. Not for training the neural network. But just seeing how it behaves in various situations, to find it's flaws, and see if it's ready for the road.

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.

It's neat that one person did that. But debugging on-highway? Bad idea.

Finding a safe place to test an autonomous vehicle on a budget is hard, but not impossible. Our initial testing in 2004 was in a large unused Sun parking lot in Fremont.[1] (Sun got carried away with expansion plans, and started building a big facility there. They paved the parking lots and poured the building foundations, then stopped construction.) Later off-road testing was at the Woodside Horse Park. We also looked into testing at the Hollister off-road vehicle park, and discovered we could book a sizable area on a weekday for our exclusive use. We never used that, though. We'd also looked into using the old FMC tank test track in San Jose, but never found a good contact there.

The 21" monitor portrait-style in the car is fantastic. The testing of a hacked-together system on the public road is not. He probably won't kill anyone, but if he were to I suspect he'd get the book thrown at him in the way that everyday death-by-DUI drivers don't. Actually I'll go futher with this criticism: we've just seen drones being FAA regulated because users were unable to refrain from doing dangerous or nuis…

But unlike drones, he is in the vehicle the entire time and can easily intervene.

The article does a good job of explaining the inherent danger someone (and those around him) faces when attempting something like this. The point is that he's attempting to push the boundaries and not asking for permission -- generally the conditions required to innovate. Maybe that should be celebrated before you bust out the "b-b-but it's dangerous!"

Is it so much to ask that people don't keep erroneously stating he built the car? The car he used was an off-the-shelf component.

I don't follow why AI vehicles need to be 100% good. Plain old human-driven vehicles sure aren't and we accept their utility as being worth the trade.

In one word: liability.

In two words: actuarial tables

Throughout history there are many cases of the lone tinkerer who achieves the breakthrough going up against much better funded adversaries. Take the case of the Wright Brothers who faced two well funded adversaries. Samuel Pierpont Langley had a chair at Harvard, worked at the Smithsonian and had among others funding him $50K from the US War Department. Alexander Graham Bell, the inventor of the telephone, was an avi…

Tracing the Wright's development process, it's the first example I know of of a directed research and development program. The Wrights formulated a clear goal, identified the problems needing solutions, developed a series of prototypes aimed at proving each solution, did laboratory experiments to resolve others, invented physical theories to resolve still more, carefully documented their progress, etc. I.e. they did…

I agree, but the Wright's went counter to common thought at the time. Like Peter Thiel's favorite question, what do you believe that few else do?

Ever since I played around with Prolog in the nineties I came to believe, just like digital eventually triumphed over analog, that neural networks will eventually triumph over rule sets based software. I did not know when it will become apparent, but I firmly believe that it is coming.

Congrats geohot. Come up with a good development framework for people to build on and it would be awesome. This is good innovation and engineering.

Like the article said it sure beats writing code to make people click ads or fixing some obscure deadbeat bug in some useless software which nobody uses.
