How hackers ruin everything with computers

&#62; Revolutionary jets like the SR-71 or the 747 took months to design.<p>Yes, and without computer assisted modelling, when they wanted to try out something - say, reducing trim drag by moving the center of gravity further aft - they had to just try it out in the field. That experiment killed one pilot, and it's a miracle the other survived. What caused that death? Engine unstart. Why was unstart a problem on the SR-71? Because its analogue computers couldn't always keep up.<p>All in all a spectacularly bad example, CAD would have saved lives, and despite his ranting it DID have a computer on board, and when that was replaced with a digital computer system it increased the reliability and safety of the plane.<p>Here's the story from the survivor if anyone's interested: <a href="http://www.alexisparkinn.com/sr-71_break-up.htm" rel="nofollow">http://www.alexisparkinn.com/sr-71_break-up.htm</a>

<i>Does anyone believe a modern Benz will be able to drive for 1,000,000 miles the way old ones regularly would? I don’t.</i><p>I think this has to do with the advances in material sciences and engineering. My theory is that parts in old cars were massively overengineered because the variation in quality was so high. If you wanted <i>most</i> of your cars to last 100,000 miles, you had to construct a car to last 1,000,000 miles. Nowadays, you can probably get away with constructing a car to last 200,000 miles.<p>Can someone with the right background comment on this train of thoughts?

I bought my phone for the non-phone features, sure I'll admit it. In fact, I never had a use for a cellphone until you could browse the net on one. When that came along, I was all in. For me it's not a parlour trick, it's the primary reason I have one.

"I make no secret of the fact that I think real technological progress has slowed in many fields, possibly even reversing itself." states the author at the start. That's very hard to defend.<p>However, let me boldly agree in that I think this is true for qualitative change, but not quantitative. I think quantitative changes are rapidly happening, and that's because it's very easy to generate better answers from a set of pre-existing knowledge. Computers (plus their engineers) are very good at that. It's the whole premise of the Semantic Web.<p>The hard thing to do is generate a better set of existing knowledge, and then curating it well. As (perhaps mis-used but I'll use it anyways) Picasso said "Computers are useless. They can only give you answers."

The fine author brags about how he could access the internet on his calculator, and sneers at people who buy phones to do the same?

The author's rant is mostly crotchety nonsense, but it was worth it for the link [1] to Harry Plinkett's hilarious and spot-on critique of Star Wars Episode III.<p>[1] <a href="http://www.redlettermedia.com/plinkett.html" rel="nofollow">http://www.redlettermedia.com/plinkett.html</a>

It'd be interesting to know the price drop over time of the cars. I'm sure that cars nowadays are more cheaper than back when they could get a million miles, so the comparison doesn't work.
