The whole internet is full of thoughts like "Ethereum may dye, because DAO was hacked".

To explain simply, my view of the situation is the following:
When a security or financial system of big banks/organizations is compromised and they are robbed or bankrupted, the main monetary system stays mostly intact or at least alive (with some inflation and less value). Certainly in this case the bank/organization is DAO and the monetary system/currency - Ethereum.
Also we know, Ethereum had no security problems, but the DAO itself.

So guys, how do you think, do I see the whole picture or am I missing something very important in case of the cryptocurrencies that is very different from fiat systems and really meters? Is there a fat chance a fat cryptocurrency like Ethereum may die ever because of the security reasons? Is there a precedent of happening this with any other altcoins?

P.S. I am new to this world and BitcoinTalk, all your knowledge and thoughts, any comment are highly appreciated!
