    The astonishment is only matched by the hubris of Uber testing of self-driving cars on public roads.

    it is odd that we used to be so conscious of our privacy and now, in the quest for likes and brags, we freely and wontonly give up our locations, friends, politics, etc. to anyone and eveyone that wants to see it...

    I think self-driving cars should be painted fluorescent orange by law.

    ...right before being placed in the crusher.

    It might come to that. In spite of all the great technology I think this loaf should remain in the oven for a while longer.

    Great technology? Nah. Proof that just because something CAN be done, doesn’t mean it SHOULD be done.

    Trust me on this... if you see one coming, and about to turn into the crosswalk that you are walking through, never, EVER, drop something and then bend down to pick it up. Fortunately, I saw the fool thing turning just in time to jump back out of the way, as I have no desire to be on the 11 PM news.

    The concept of self-driving cars is always sold in terms of what we don't like about human driving, which is the 0th stupidity in the drumbeat for their adoption. It turns out that what a human brings to the intelligence of the driving process is immense perceptive, computational, learning, and decision-making power, beginning with the fact that life instinctively protects life, including its life and other lives. The smartest computer is still a psychopath; it cares about nothing and cannot care about anything.

    The smartest people will tell you there is a limit to what intelligence can do. Stupidity, OTOH, has no such limit.

    Have you ever driven the Schuylkill Expressway at rush hour?

    Yup.

    Many of those drivers aren’t human. They’re something else, all right... :p

    On top of that, computer programming entails the careful eradication of weird corner cases. You must guarantee that your program provides the correct output for all valid inputs, and that it can also handle any possible input without behaving terribly.

    A lot of security vulnerabilities and attacks are possible because someone didn't account for a weird input, for example the Heartbleed bug { please send back the first 50,000-characters of "HELLO" }. Attackers can create those conditions and cause a disaster---or sometimes corner cases can just happen, like Telsas accelerating into firetrucks, or a malfunctioning stall sensor in the Boeing 737 Max.

    But what happens when we replace a precisely defined program with AI? Now you input a bunch of camera and sensor inputs, and the trained AI recognizes an obstacle. What are the corner cases? What weird inputs are not being accounted for in the training data, and will cause a false decision? What is the process for guaranteeing that the program works in general, and not just a common case?
