I don't think we will get to that, because I think humans will adjust their thinking as events worsen. But perhaps I am underestimating how engrained the mindset is that believes in government.
If we say gigadeaths, most people would dismiss us as kooks.
In any case, the features we need in a better crypto-currency have far reaching synergies in positive ways such as micro payments and fostering new paradigms in knowledge and social interaction on the internet.
So we don't need such a dire scenario of Armageddon, in order to drive a desire for a better crypto-currency than Bitcoin.
How powerful a scenario will be needed in order to counter the pervasive nature of the reality that's generally accepted today...
To what extent can any knowledge paradigm be introduced that can counter the pretty lights and repeating patterns and alluring whispers? How can 100s of millions of people come to accept, within any measurable amount of time within their own lifetime, that most of what they've come to accept as knowing or caring about within that frame of time is incorrect? How can I convince Erich that his fascination with Call of Duty is completely meaningless, and he should instead learn about finance like he said he wanted? How do I tell Erica that she should probably have gone to nursing school instead of marrying that wifebeater that she ended up with? These people have left society in pursuit of completely useless efforts, and instead chose to live as simpler animals. How can one hope to reason that that's incorrect? I've yet to be shown that the faith in humane efforts can go that far . . as I'm not convinced that they are physically capable of going that far.
Think about it . . with IQ tests, multi-tiered verification of intelligence through Associate's, Bachelor's, Masters, Phd's, tens of thousands of further tiered certifications . . it's impossible to refute that there's a distinctive bell curve present in human capacity and desire for knowledge. With the appearance of such a curve . . one so perfectly conforming to probability . . how can this go any further . . when that very appearance of the bell implies that the potential is maximized? There used to be a very low bar for everyone to pass. What we have now may very well be the extent of what humanity can manifest . . knowledge wise. There's just no more juice. That's not to say that the pursuit of knowledge is dead, only that it's pursuit by the majority of the population is exhausted. The majority of what we're left with is debt farms.
With television, video games, endless supplies of pornography, limitless troughs of food of infinite varieties, consumer culture, and an otherwise bottomless supply of past-times . . what shift in paradigm could possibly be manifested that would foster a particular interest for integration, differentiation, chemistry, physics, programming languages, manufacturing processes, computer architecture, astronomy, creation of art, cryptocurrencies, conceptual drawing, or pursuit of other true knowledge?
Underestimating? I fear most that hive-mind is the mind, not the mindset . . that for the first time in history the hive is set to become the world rather than towns, states, countries combined. I also fear that I don't know whether or not that's something to fear at all.
Removing the Armageddon scenario from this situation requires an insurmountable force . . which may very well come to be the crypto-currency you mention. I know it's not Bitcoin, but all I can continue to do is keep reading until it decides to show itself . . or given infinite time I'll make it myself.
