There are exceptions - Calculus is a good example, That's why everyone knows the name Newton more than three centuries after his death, calculus and his laws of motion enabled the leap called the industrial revolution and inspired the social leap known as the enlightenment.

It's like expecting Google search to suddenly gain sentience

Meet Watson, it beat the best humans in the open ended problem domain of "game show trivia" using natural language processing. When it won the Jeopardy championship it had 20 tons of air-conditioning and a room full of servers. Today it runs on a "pizza box" server and you can try it out yourself. After Jeopardy it went back to working with various medical institutes where it was trained and fed on a steady diet of medical journals, it's now well past the point where it became knowledgeable enough to pass the test for a US GP's license.

True Watson is blind, but I suspect the problems with visual input is more about the human teacher's failure to provide the right context and experience than it is about the artificial students ability to learn.

>The documents DEMAND that the the press DESTROY SONY!

Is this a joke that whooshed over my head, or are you hopped up on something? I'm thinking it's probably the former.

Information wants to be free. Sony demands. Anthropomorphism requires.

If we look at jet aircraft, wear depends on the airframe and the engines, and the airframe seems to be the number of pressurize/depressurize cycles as well as the running hours. Engines get swapped out routinely but when the airframe has enough stress it's time to retire the aircraft lest it suffer catastrophic failure. Rockets are different in scale (much greater stresses) but we can expect the failure points due to age to be those two, with the addition of one main rocket-specific failure point: cryogenic tanks.

How long each will be reliable can be established using ground-based environmental testing. Nobody has the numbers for Falcon 9R yet.

Weight vs. reusable life will become a design decision in rocket design.

Isn't this something everyone already knew, radical warmists and evil deniers alike?

Maybe, but statistical thinking doesn't come naturally. People cheat at gambling by loading dice so that they come up snake eyes (say) 1 in 20 throws. They get away with it because even if you know the dice are loaded there is no way to link any particular snake eye event to the hidden weights. The victims simply subscribe it to luck, but the longer you play the more suspicious they will become of your "lucky streak". Same deal with storms, floods, and droughts.

Statistics are no substitute for judgement. -- Henry Clay
