The power efficiency of computing has improved by a factor of a billion from the ENIAC computer of the 1950s to today's handheld devices. Fundamental physics indicates that it should be possible to compute even another billion times more efficiently. That would put the power of all of today's present computers in the palm of your hand. That says to me that the age of computing really hasn't even begun yet.
When we show people that something is possible that they didn't think was possible it does more than just change things. It changes the way people think about the possibility of things changing. It helps them see that life is not the same day-after day, unsurprising, unending drudgery that so much of life teaches them that it is. And that is a huge contribution to their humanity.
Men should not labor foolishly like brutes, but the brain and the body should always, or as much as possible, work and rest together, and then the work will be of such a kind that when the body is hungry the brain will be hungry also, and the same food will suffice for both; otherwise the food which repairs the waste energy of the overwrought body will oppress the sedentary brain, and the degenerate scholar will come to esteem all food vulgar, and all getting a living drudgery.
