- DmenshunlAnlsis 8y agoOur eyes are incredibly advanced compared to any camera in existence, and hooked up to a real life AGI, and we still fuck up. No comparison. We meatbags are still far more sophisticated and battle tested than anything said meatbags managed to build, which is why so much of our building attempts to replicate our own capabilities.

- TeMPOraL 8y agoYeah, and they do that with dozens of years of accumulated knowledge. Do not have the impression that what you perceive with your eyes is the photons hitting your retina. All that input is heavily fused with decades of experience in dealing with people and the world.

- ethbro 8y agoWhere I'm from, small humans typically locomote with around 6-10 months of life experience. And fairly reliably. YMMV
- TeMPOraL 8y agoWould you be fine with letting a 10 months old walk around town unsupervised? Or drive a car?
- ethbro 8y agoIf I trained a child to drive, I'd be comfortable letting them drive at 6. I believe I was around that age the first time I drove (handling steering, with assistance on gas / brake). My memory is that the only difficult part was a lack of power steering on hilly terrain. Same age for walking around town unsupervised: the Japanese do and don't seem to lose many. My original point was focused on the technical feasibility of driving with limited sensor input, which is physically possible. Whether or not it takes a week, a month, or a million experience-years is a computational and algorithm problem. All of which (based on previous technological progression) appear to be tractable.
- TeMPOraL 8y agoAnd my point is that it's not just about experience-years, it's also about the breadth of knowledge. When driving, humans do not use just the experience acquired from looking at things from behind the wheel. They also use their general understanding of physics, of materials, of concepts related to visibility, traction, not to mention expected behaviour of other people and how to read face expressions.
- ethbro 8y agoFor an average driver, I'd call BS on that. Humans are terrible at learning complicated things they rarely have to recall. E.g. the disaster that is the first major snowfall, every year, or automatic transmissions, antilock brakes, and traction control systems becoming standard The human can only reliably be trusted to keep the car between the lines, stop appropriately, and occasionally make turns. Which is something much simpler to compete with!

- ethbro 8y agoAs someone who works in the field, I'd offer two points. Our intuition about the future is linear. But the reality of information technology is exponential, and that makes a profound difference. If I take 30 steps linearly, I get to 30. If I take 30 steps exponentially, I get to a billion. - Ray Kurzweil People once said the same thing about fire lances.
