Well, that, and because our airplane network is spectacular and (relatively) low cost.
Anyone can learn to optimize algorithms. It takes wisdom to know when and why to do so. Anyone can learn to write a sort function. It takes experience to know which one to choose, and why... and not only that, why it matters. Anyone who programs will eventually learn how to debug their mistakes. It takes insight to learn the Tao of the Debugger.
It's possible for someone to learn these things on their own (obviously the first hackers did somehow, eventually), but if you learn them early, from someone that you deeply respect, a) the lessons *stick*, and b) you don't have to spend your time and effort learning them on the job later, so you have time to focus on all the other things you need to learn to do whatever you end up doing.
Most people seem to have a pretty bad attachment to actual historical fact, preferring shiny objects.
So the answer is: your eye compensates via a number of mechanisms not available to cameras.
So "[getting] to be half as near as good as peoples [sic] eyes" will require an improvement in cameras of about 500,000 times.
1/2 of all suicides are done with guns in the U.S (17,000 out of 34,000). Yet, the U.S. suicide rate is completely typical for Western European counties where there are almost no guns (and where guns are rarely used for suicide).
The only reasonable conclusion is that guns are just the most convenient and certain method that happens to be available to suicidal people in the U.S.
People do own their own genes, as they occur in their bodies.
A patent on a gene covers the isolated and purified gene but does not cover the gene as it occurs in nature. Thus, the concern that a person whose body ``includes'' a patented gene could infringe the patent is misfounded. The body does not contain the patented, isolated and purified gene because genes in the body are not in the patented, isolated and purified form. When the patent issued for purified adrenaline about one hundred years ago, people did not infringe the patent merely because their bodies naturally included unpurified adrenaline.
It doesn't matter whether the difference between sample A and sample B is real or perceived, because when I'm actually listening to music, that is 100% perception, and I *do* know (or think I know) a priori which sample I'm listening to.
The scientific approach is great (mandatory, really) when you're doing science. I will go beyond saying that it doesn't actually help much at all with determining what you will enjoy. I assert that more often than not it actively *decreases* your enjoyment of the experience itself.
Of course, one can certainly enjoy understanding and appreciating the science behind it, leading to more enjoyment overall... I'm speaking purely of the perceptual portion of the experience.
That seems much more feasible than what is implied by the title of this post.
Of course, maybe that just means the universe is acausal. Weird, and a bit troublesome for our puny simian brains to wrap themselves around, but I suppose the universe doesn't care.
Current solar panels wouldn't work due to weight, but you could imagine the roll-to-roll printed photovoltaics that have been talked about being doable.
