Frankly, the DAO fiasco killed Ethereum for most people on its own, everything else was icing on the cake. This was Ethereum's first real "smart contract" that did something you couldn't really do without it, and it failed quickly and miserably, showing most reasonable people that they can't trust smart contracts to do what even their creators believe that they do. At least with a legal contract, the intent of the people agreeing on it matters.
