		<summary type="text">It manufactures unemployment, or so says an old friend.  The argument is not much more than what he describes as the agreeable Luddite one: that there is a perpetual pressure to cut costs and raise profits.  “Unregulated capitalism”, whatever that is, races to eliminate employees.  (How much more there is to the argument is hard to say, since the posting has become non-public.)  

	One response to such profundity is to match it with the observation that this looks at only one side of the coin.  Capitalist economies also manufacture employment.  (Few people hire others out of altruism.  Few people can build lots of stuff without others’ help.)  They also manufacture stuff.  Lots and lots of stuff, which people want to buy.  (Few people give others tons of stuff out of altruism.)  When unnecessary costs are cut, customers and shareholders benefit.

	The system is obviously in constant change, only roughly stable, and is unlikely to ever converge to a steady state some might idolize, where some economic status quo simply persists.  In order to force a utopian order, it would require a level of control and force that would be familiar to those who studied totalitarian states.  And there is no other endpoint possible.  At any intermediate state, there will be some perceived “social injustice” that requires more force to “solve”.  People who promote just a little more regulation should be expected to state their ultimate end-point: what is the maximum power for the state beyond which they would not advocate.

	(The dual situation exists with us laissez-faire types.  I would like a smaller state, less control, less competition with the private sector.  How much less?  A good first step would be balancing the darned government budgets.)</summary>

		<summary type="text">Freshly released is this investigation final report for an Airbus accident from 2008.  In this event, the on-board computers spontaneously messed up during a routine flight, and harshly pitched the plane down for a second or two.  This threw around unrestrained passengers and crew in the back, crashing them up to the ceiling.  More than a hundred got injured, some seriously.  The captain of the plane responded perfectly: declared an emergency, and diverted to the nearest suitable airport.  He did not trust the avionics any more: He then flew the aircraft without the autopilot or autothrust engaged, and using the standby instruments, for the remainder of the flight.

	The bit that bugs me more is the root-cause-analysis and correction of the bugs in the system.  The final report unnervingly qualifies this: The failure mode was probably initiated by a single, rare type of internal or external trigger event …
The spikes in the ADR parameters were probably introduced within the CPU module …
A much more likely scenario was that a marginal hardware weakness of some form made the units susceptible to the effects of some type of environmental factor, which triggered the failure mode.

	It goes on like that.  They’ve done some impressive analysis of the systems, but the there is quite a collection of maybes and probablys.

	But be reassured: The occurrence was the only known example where this design limitation led to a pitch-down command in over 28 million flight hours on A330/A340 aircraft. ...
It is widely accepted that not all the potential failure modes and failure scenarios for complex systems can be identified in practice, and fault-tolerant design features are included in a system to reduce the risk of such problems. ...
The ADIRU manufacturer conducted a ‘theoretical analysis’ of the potential for a single event upset (SEU) on the LTN-101 ADIRU. The overall result of this analysis was that [...] the ADIRU still met the aircraft manufacturer’s safety objectives …
As a result of this redesign, passengers, crew and operators can be confident that the same type of accident will not reoccur.

	It’s an uneasy situation.  Having a sense of how much technology and effort goes into this sort of machinery, it’s clear that there are failure scenarios that we don’t know we don’t know.  And yet we fly.</summary>

<b>UPDATE2</b>: Wretchard <a href="http://pjmedia.com/richardfernandez/2011/12/27/if-tomorrow-comes/">recaps</a>.</p><blockquote style="background: #eee">The world faces a danger more terrible than the worst Green imaginings. The European environmentalist who wants to shrink the world&#8217;s population to reduce carbon emissions will spend her declining years in misery, for there will not be enough Europeans alive a generation from now to pay for her pension and medical care. For the first time in world history, the birth rate of the whole developed world is well below replacement, and a significant part of it has passed the demographic point of no return.</blockquote>
<blockquote style="background: #eee">But not only the religious need the hope of immortality. The most atheistic communist hopes that his memory will live on in the heart of a grateful proletariat. Even if we do not believe that our soul will have a place in heaven or that we shall be resurrected in the flesh, we nonetheless believe that something of ourselves will remain, in the form of progeny, memories, or consequences of actions, and that this something will persist as long as people who are like us continue to inhabit the Earth.</blockquote>
<blockquote style="background: #eee">Human beings may not be the only animals who are sentient of death. (Elephants evidently grieve for their dead, and dogs mourn their dead masters.) But we are the only animals whose sense of continuity depends on culture as much as it does upon genes. Unlike men and women, healthy animals universally show an instinct for self-preservation and the propagation of their species. We do not observe cats deciding not to have kittens the better to pursue their careers as mousers. </blockquote>
