Perhaps a relevant question is whether this is caused by a bug in Ethereum itself or just someone using Ethereum wrong. The Bitcoin developers have rolled back transactions that were caused by a bug in Bitcoin itself but they do not intervene in the many cases of user error.<p>Arguably, Solidity makes it so hard to write secure contracts that it is negligent. If the Ethereum team decides to take responsibility for The DAO, I hope they fix Solidity once and for all, not just bail out this one contract.
This bailout has some similarities to the financial crisis. Of course ethereum doesn't seem to need the DAO to function. Bailing the DAO investors out voids a valuable lesson.
