Note also that secularists in particular tend to be very selective in presenting this as a case of Gallileo being persecuted only for the things that he was right about, while conveniently forgetting that the things he was wrong about (which he also insisted were facts) also played a significant role in his trial, including his theory about tides, which even his most ardent followers were embarrassed by due to the fact that it completely failed to explain observed phenomena such as there being two tides a day instead of only one. It's also quite possible that they'd have ignored him but for the fact that his published "Dialogues" had a character called "Simplicio" who was obviously based on the Pope, and played the idiot to another character that was an equally obvious stand-in for Galileo himself. Those who seek lots of trouble in a society where certain people have near absolute power over them will find that publishing a work which presents one of those people as a blithering idiot is an excellent way of finding it.

    If popularity is the key, then please explain why several pieces of malware (primarily viruses) for older non-Unix versions of Mac OS appeared during periods when its popularity was at a notable low ebb. Popularity gives people a reason for attacking a system, but whether they succeed or not is governed by how good a system's defences are, and with general purpose desktop computers in particular, users are a part of those defences because they ultimately control what does or does not get installed and run. To use Slashdot's much-beloved car analogy, a designer can reduce the probability of accidents by giving a vehicle superb brakes and steering, sensors that adjust to varying road conditions, lights than turn themselves on during rain, fog, and encroaching darkness, audible warnings of being too close to other vehicles, etc., but the fact that there's ultimately a human behind the wheel means that people can and will do stupid things, so our designer also puts seat belts and air bags in to increase the probability of the occupants surviving the consequences of both their own silly acts and those of others.

    "Maybe one System is more secure than the other, maybe one company manages to get patches out the door faster than the other (though I do like the fact that I don't have to rely on one single company for the delivery of patches), but nobody is immune to zero day attacks."

    Agreed in full. It's impossible for even the most talented group of people to build something as complex as a complete modern OS without making (a probably quite large number of) bad design decisions and programming errors, and this situation is compounded by the fact that the OS authors have no control over the thousands of third party applications, widgets, and other stuff that people want to put on their computers, the vast majority of which will also have their own share of bad design decisions and programming errors. What's surprising therefore is not that all there are, and will inevitably be security holes that can be exploited, but the fact that such complex combinations of elements from so many different sources work reliably enough for people like me to experience significant periods of up-time in Linux, OS X, and Windows XP.

    So as you say, the best we can hope for is that vulnerabilities get found and patched before they're exploited, or failing that, are closed very shortly after an exploit appears, at least until somebody finds a way of preventing social engineering attacks like this one without frustrating and annoying users with Vista-style items such as "Your computer is about to do something that you may or may not have wanted it to do.

Lethal childhood diseases were still prevalent even in the first world well into the 20th century -- my mother for example was born in London in 1928, and caught throat diphtheria as a small child. She obviously survived, but some of her friends didn't, and most people knew families who'd lost kids to whooping cough, polio (which frequently permanently crippled those who survived it), and various other "fevers" of an undefined nature. This was a time when medical knowledge was significantly more advanced than during the Middle Ages, so children afflicted with such ailments stood a much better chance of surviving, but diphtheria alone still killed around 10% to 15% of children who were infected by it in both the US and UK during the 1920s (it's estimated to have killed around 15,000 in the US during that decade, of which the vast majority were children).

    The fact that our main children's health worries in the 1st world are things like obesity, low self esteem, and Attention Deficit Disorder serves to indicate how far we've come in a period short enough for there to people still living who remember a time when the children of even wealthy families could easily become infected with one of several potentially lethal diseases.

At some point, something's got to give: the ECB has to drop interest rates; wages have to go up considerably in Southern Europe (thereby further increasing inflationary pressure); or a recession occurs in some parts of Southern and Eastern Europe, further accentuating the already considerable differences between various European economies, and making the ECB's job even harder.

Human activity wouldn't be considered as a factor because the few stone tools and rare fossil examples of humans (fossilisation only happens under specific sets of conditions) would indicate that these fragile creatures with a primitive technology wouldn't have been a significant threat to powerful predators like bears, lions, tigers, etc., and their presence wouldn't explain the fact that marine ecosystems all over the planet also began to collapse within a few tens of years. Yet the only evidence they have to go on are a few fossils of skeletons that provide only tenuous clues to how any of their original owners lived, moved, or behaved, and none whatsoever that help explain why so many of them died in such a short period of time.

    It's likely that these future palaeontologists would also come up with all sorts of theories to explain how it happened, most if not all of which would be incorrect because all the evidence that points to the real causes has been erased by the planet itself over a period of time that's far too long for any intelligent creature with less than a near infinite life span to grasp. Consider for example how little we really know about Neanderthals in general, and their extinction in particular, and then consider that they were far more like us than 99.9999999% of all the other life that's existed (and indeed still exists) on this planet, and only died out 30,000 years ago, one 20,000th of the time between now and the K-T extinction event.

    "But as for the fascination with the Cretaceous mass extinction -- I think it comes directly from our fascination with dinosaurs... the enormous and toothy types scare the bejesus out of us, to put it one way, and it's perhaps even more awe-inspiring to think of them all being wiped out than it is to imagine them alive."

    It could also possibly be due to the fact that some palaeontologists (and the popular press) are of the opinion that the K-T extinction vacated various ecological niches which allowed mammals to proliferate and evolve into a wide variety of forms, some of which rivalled even the big sauropod dinosaurs in size and weight, while others would eventually lead to us. I'm not personally convinced that significant mammalian evolution wouldn't have occurred even if the dinosaurs hadn't died out, just as crocodilians, snakes, birds, lizards, turtles, amphibians, and many other forms of life also co-existed with and continued to evolve alongside them. Recent fossil discoveries of cretaceous mammals have overturned the old view of them all being tiny shrew-like nocturn
