Same with best uber drivers.

  Any human is the product of eons of natural selection honing our perception and reflexes. The process was unpleasant.

    I think if you look at evolution more closely you'll see that it is messy and is constantly creating dead-ends. Mammals were insignificant until an extinction event occurred. It's not like we were superior and displaced the dinosaurs. We have lots of errors and junk DNA. We make all kinds of mistakes. Perhaps not fatal ones yet, we'll see how climate change plays out. As for our perception and reflexes... I wouldn't brag that they're that good just because they haven't been bad enough to cause our extinction.

      > I think if you look at evolution more closely you'll see that it is messy and is constantly creating dead-ends. That's my point. The natural selection process for self-driving automobiles is just beginning, as they meet the challenge of the real world. I'm concerned that it is going to mirror the messiness that biological evolution involves.

    But only two or three generations with automobiles

    Sure there is ~200,000 years of natural selection. That probably 10,000 generations of learning assuming 20 years. But computers can run 10,000 simulations to learn in minutes. And obviously we are not going to create a autonomous driving ability in minutes but we can speed up the learning evolution significantly in machine world vs humans that have 10-50 years per evolutionary learning event. My view is the hard thing about autonomous driving will be the change in style of accidents. Even if autonomous driving has half of human accidents we will probably see things that to the human eye seem really obvious so people will be 'if it can't predict that why should I trust it' type thing. But we won't see the many accidents a computer avoids that a human would make or finds obvious. I'm positive about it but suspect we will see the roll out take many decades as it starts in cities with the right conditions, moves to trucking routes but will probably take some time for national metro coverage.

      I think that you overlook the fact that a tremendous amount of evolution went on before humans came onto the scene ~200k years ago.
      • Gustomaximus 7y ago
        I was waiting for that :). Let's put it out at billions of generations for pre-human evolution. Point stands. I computer will do millions of simulations in a day. And be done across a population far greater than historic evolution. Doesn't take long to get billions of learning events. On top of which evolution pre-intelligence (as a very loose term) was somewhat random, where our systems are starting from a much more evolved position that does take advantage of existing evolution as much as humans do.

          Not really- a single base-pair can change the entire tertiary structure of a protein. Which is something computers are not great at predicting. Depending on how you calculate it, 1 "cycle" of life can be worth trillions^2 or more cpu cycles. It's a meaningless comparison, as presented.

    Is unpleasant, natural selection hasn't magically stopped.
