I dont buy that. Vision developed for different purpose than to provide full HD sharp vision across entire FOV. It has great pattern recognition and peripheral motion detection. It heals itself. It has low power consumption. It does not overheat and can work in many environments, even under water.

Modern competition like Go PRO require too much baby sitting, and can hardly work for 2 hours without maintenance.

You don't buy what exactly? This is just science on how eyes work and some of the interesting things that happen, the author isn't being prescriptive about what eyes are for or how they should be used. I think what you said is entirely consistent with the Twitter thread.

I think OP does not buy that camera system is better than eyes or that our vision system is bullshit insane.

[rcxdude]

I mean, I don't think the point is that cameras a better overall (apart from the advantages mentioned above, our eyes still have a ridiculously good dynamic range compared to cameras), just that if you want a predictable mapping from stimulus to result, our vision system (which is eyes + visual cortex) has a ton of quirks and biases which affect perception in ways which are really non-obvious and can really obscure what's actually happening (hence 'insane'), while cameras are far more predictable and regular, which can matter if you want to be precise about what's going on.

> low power consumption

Hmm, well the visual cortex makes up almost a third of our entire brain, and the brain uses ~20% of our daily energy. I’d hardly call that “low power”! Though granted I don’t imagine you can break a sweat just from thinking.

> I don’t imagine you can break a sweat just from thinking

I heard that people who were asked to do sorting tasks, i.e. just separate big oranges from small ones, got tired as heck, comparably to physical workers. Then again, dunno about sweat.

[just-ok]

Yep, mental exhaustion is undoubtedly a thing! I'd love to see how heart rates change with something like test question difficulty. Since sweat is generally a product of heat and occurs when your heart works harder during exercise, I wonder if the heart also works harder to pump the brain with more oxygen to enable it to... think harder? Obviously just musing, am no physiology expert.

I would definitely call that low power. Our entire brains only use 20 watts of power, compare that to the 85,000 Watts IBM's Watson uses.

[rewoi]

What is an alternative for example for driving? Computer and lidar that needs a kilowatt just to do single task, not universal?
