EOS is like the first operating system for block chain. Prior to EOS, all development has been done in "assembler code" if we use a computer analogy. If your program locks, well a program controls the whole system in blockchain tech, have to reboot the computer... (hard fork in blockchain tech). With EOS, you got an underlying framework, and on top of it, you build applications. If your application crashes (like the DAO) no need to hard fork the network to fix it, EOS provides solutions while keeping the system operational. It also handles Bitshares / Steemit volume in terms of transactions per second, which Ethereum will never do. With Ethereum if any one token has an issue that the Ethereum foundation thinks needs fixing, they're going to have to fork the protocol to fix it... every time. More features with EOS too besides this since Bitshares has the best account management setup.
