"His self-funded experiment could end with Hotz humbly going back to knock on Google’s door for a job." The biggest thing here IMO is this is self-funded. Any startup trying to do what he is doing in this environment would have raised $50 Million, hired 100's of engineers from top notch schools, become accepted in YC, and have Marc Andreessen, Paul Graham, Sam Altman and all singing their praises. Kudos to him for be…

I wish I could upvote this more. A person in their 20's knows nothing, but thinks they've outsmarted the world. It's not until your 30's that you realize how big of an idiot you were/are and how much of the world you actually understand (read: little).

"I know everything there is to know." I kind of took that to be like how Musk talks about needing to know first principles. In the article you can see that he was humble about what he thought he knew, took jobs here and there and eventually confirmed that he was at the cutting edge, that he knew 'everything there is to know' about this special area. That's when he realized that he was qualified to try this. IMO, anyw…

Probably really bad now, or doesn't react at all and also probably will collide in critical and dangerous positions. But that is also not the future. The future is how does it interact in non-dangerous positions long-term while other cars are self-driving in compliance.
Is it that hard to detect a clear danger like a car that suddenly stopped in front of you on the highway?
He uses an artificial neural network to make the driving decisions.
You train them by showing millions of situations (images of the surroundings, information about the cars current state and information about the imminent past in this case) and the wanted reactions/solution/answer (how to drive in this case). Hotz probably has enough "normal" data, because you hold the line all the time when driving and apparently there were enough situations where the car in front slowed down and he slowed down.
From the latter case you could guess that the car would break more rapidly if the car in front stops more rapidly than in the training sessions with a human driver (you would have to test that, as you usually cannot just look at the trained neural network and see that, because they become insanely complex after a certain depth).
But probably the car never "saw" bricks falling of the truck before you or even a kid running from the left side. Those are edge cases, that are unlikely to happen, especially on a motor way. But I'd still like to know whether his software would just apply the nearest trained case and see it as noise, or notice that something is off here and alarm the driver.
Definitely a cool project, don't get me wrong. But I get kind of sad when the work of thousands of scientists who worked on the theory and the work of Tesla, Google and big car manufacturers gets dismissed by "but look at this guy" (in general, not directed at you).

Why is the first comment on HN minimizing this truly impressive project? Of course it's not perfect, he's ONE person.
Because this article reinforces our bizarre cultural notion that one person deserves all the credit for some innovation. Nevermind the ridiculous amount of engineering that was required to build all the tools he's using and the order of magnitude more engineering required to make this a safe, mass producible product. But nah, let's just praise the founder, allow him to get rich while we all do the dirty work.
Your comment screams a superiority complex, but I bet that you are actually a nice person in real-life. Hotz is doing good work, and everyone in the technical field is relying on work done decades before they were born.

He built an impressive prototype, considering he hacked it together in a month. This is just the start, not the end.
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.

This whole: "Twenty year olds don't know shit but 30 year olds are so enlightened" sentiment needs to stop. I agree that many younger people think they understand more than they do but that's just part of growing up and we all go through it.

Look at any automated warehouse these days. Pickers, stockers, warehouse managers..... Those are going by the way side.
Would you consider those machines AI?

I don't disagree with that. I've worked with some very smart people in my 20s who sounded similar to Hotz -- enthusiastic, retrospectively naive about their understanding of a field, but above all, superbly intelligent. They did really great things, things that maybe didn't work perfectly or as envisioned, but still things that might scared off more experienced folks. But also now that I am in my 30s, and they are as…
There have been people in my past that wanted to start a project that I didn't think they were capable of finishing, because either it was too large, they didn't have the skills/smarts (not that I thought they were stupid, just that I thought it would take exceptional intelligence), or both. A few of them succeeded, either in the original task, or the effort and journey was well worth the price paid. Part of this was…
I do remember being about 19 and thinking I was the best programmer in the world. By about 22 I had rewritten as much of my old code as I possibly could because it was so horrible. Somewhere between there and now I've gotten a cynical bit of humility to tamper my ego. I think the cynical part is that my ambition has not lessened, just my belief that I can succeed.
One Steve Jobs philosophy is focus and say no. I'm guessing I could do better if I said no to all but a single project.
