Based on what? Humans run in to cyclists too and although I have know idea about Waymo's tech, in a research setting computers are better than humans at figuring out what objects are based on visual data.

If computers are so good at this, why am I (a human) asked to identify bicycles and motorcycles to train these computers when confronted with a captcha? A human needs far less training and can identify a person on a bike without ever seeing an actual bike. They can also infer what is likely to happen based on a lot of context clues. Even if an event doesn’t seem likely, I can still prepare. For example, if I see kids playing basketball in a driveway, I’m going to slow down, incase the ball bounces into the street and a kid takes off after it without looking. I don’t need to wait for the kid to be in the street to start reacting and prepare for different possibilities.

The human mind is not a viable target for hackers. The risks of human drivers are individual. The risks of computer drivers are systemic and massive. One bad bug or hack could kill millions if self driving cars become ubiquitous.

        You still don't get. All human problems are individual. Emotions in one person have zero impact on emotions in a driver two state away. Software problems are systemic. They change the entire system at once. Your "just hypothesis" dismissal would carry a lot more weight if silicon valley hadn't been cranking out bug filled garbage for the last 20 years in their move fast and break things frenzy. Kyle Vogt was (in)famous for vaunting that culture at cruise so there's no argument AVs have somehow escaped the silicon valley rot. The tech industry need to stay far, far away from anything safety related

  The computers don’t need you to do captchas anymore. The captchas are just solved problems being used to slow down bots and spammers these days.

      You're linking to discussion of an article that explains bots are solving CAPTCHA and reCAPTCHA faster and more accurately than humans. I don't understand what you are trying to say, but I don't think it aligns with the evidence you're providing.

        You mentioned… >The captchas are just solved problems being used to slow down bots and spammers these days. If bot are solving these problems faster and more accurately than humans, it’s not really slowing down the bots and spammers anymore. That is also a solved problem.
        roenxi 3y ago
        Well, if it is solving CAPTCHA better and faster than humans, that is a useful signal. Maybe they monitor how often an IP address figures something out and if it gets too many right they +1 a suspicion counter. I dunno. Implementing the CAPTCHA solving bot also takes time and expertise; it'd filter out some low-ability spammers.

  The captcha example isn't exactly fair, the images shown can be newly generatrd, repeated, or used as control images, and even if they are unclassifiable then you're not seeing the successes. Without knowing the whole system there's too much hidden bias to claim the computer is more of less accurate than a commuter.

    No doubt all of your excuses are at least partially true, however, at this point, literally after almost two decades of billions of people training these things to see bikes, it still needs a lot more work.

      Recaptcha has not been used to train any neural network to detect anything in a very long time. In fact, visual challenges like this are a mostly solved problem, and the real magic is the classification that happens behind the scenes.

        How many years or decades did we spend answering them before it got to where it today? I’m all for optimism, but these problems are clearly much harder than the futurists would like the public to believe. Elon said Teslas would be driving across the country to pick up their owners by 2018. 6 years later and what does it do, drive across a parking lot? https://twitter.com/elonmusk/status/686279251293777920 https://twitter.com/elonmusk/status/686279251293777920 Trains are also a solved problem, and seem like a much better solution to the problem. With rails, a vast majority of the complexity around driving goes away. They also remove traffic instead of keeping it the same or making it worse. Less traffic would likely mean fewer accidents, even if humans are still the ones driving. And batching transit together, with dozens of people in one vehicle is going to be far more energy efficient than everyone running their own vehicle. It also solves the issue of drunk driving, distracted driving, and bad drivers in general, as everyone is just a passenger. So much money, time, talent, and energy has gone into this self driving stuff, and it seems like a massive misallocation of resources. They’re solving the wrong problem.

  >if I see kids playing basketball in a driveway, I’m going to slow down, incase the ball bounces into the street and a kid takes off after it without looking That's because you're a thoughtful, conscientious driver. A very large fraction of drivers are not, so society winds up with lots of dead kids. Humans are terrible drivers: some of them are OK, but too many are very bad, leading to catastrophic results, and because of this human drivers need to be eliminated. Alternatively, the society could become far stricter about which humans are allowed to drive, but that isn't feasible when the society has intentionally made it so that it's effectively impossible to survive without owning and driving a car.

Seeing a bike and inferring the vector of a bike are very different. A kid or tweaker on a bike needs more frequent updates than someone commuting or training.
