I think the "everything ends" thing is a bit of an illusion really. Most of the endings were in fact periods where one form of rule or civilisation was slowly supplanted by another. In the few cases of massive civilisational crash, like the indiginous depopulation of the Americas, they were quickly supplanted by Europeans. Short of a massive plague of death I don't see a sudden collapse of modernity as being very likely, and even in that situation humanity is far more educated than it was then, and so the survivors would be far more likely to be able to maintain a vestige of civilisation and quickly re-reach old heights - perhaps within a few generations.
I do think the "too big to fail" argument holds a lot of weight too. In the past internal/external pressures were the main cause of civilisational collapse, but in those days (right up until the collapse of the USSR) we had many different isolated civilisations, whereas to a large extent we now live in one huge globe-spanning civilisation. Sure there are political differences, but the economic system is more or less global and each state relies on global stability for its own success. It's got to the point where states which are practicing self-destructive tendencies are in fact "targetted" by the rest of the global community for intervention/regime change/correction and this is largely seen as being acceptable behaviour.
Although Erikson talks about natural causes (such as a plague killing people) as a possible cause of a civilisational collapse, I think it's far more likely that economic reasons would be at the heart of it. Shortage of resources and slowly changing attitudes towards internationalism have meant that people no longer consider the future of their own country as paramount above that of others. Wars over oil, food-even water are the most likely causes of civilisational collapse, and even then it would be localised.
A common end-of-the-world scenario is that the West/developed nations, seeing the depletion of resources as a direct threat, grow ever more tyrannical in their control, leading to an end of our value system and therefore a decent into the kind of self-destructive system that killed the central american civs (in SE's essay) admittedly with less brain smashing. In the UK if you work in the Houses of Parliament you have to sign a disclaimer saying you won't try to overthrow parliamentary democracy (no, really). The basic principle is that you will, whatever your views, try and implement your plans through the current infrastructure, rather than smash the state. I think that short of a global catastrophe of epic proportions, the changes that come to our civilisation will be creeping not sudden, and will be viewed in terms of slowly changing and accepted attitudes rather than a massive doomsday.
To underline all of that rambling nonsense, the main difference between all of the civs we're digging up and the one we're trying to bury is that the one we have now has no serious external enemies, a system where power is based on mutual recognition and an economic system that demands stability and mutual support. Even the prospect of war is unlikely for the first time- not because we're less aggressive than before, just because there are few advantages to it.
