I think the basic idea is that with Bitcoin, you sort of have to hack at it to achieve any unintended functionality. These things can and do exist in the Bitcoin world, but when you get down to it, Bitcoin is meant to be a currency; anything built on top of that is just a hack that happens to work. Ethereum and its smart contracts, on the other hand, are structured to handle these sorts of extensions by design. There's nothing that Ethereum can do that Bitcoin absolutely can't be used for in some hacky way AFAIK, but it's generally much easier to do complex things with Ethereum that aren't strictly transactions of currency.

This makes sense, but I guess I just don't see much practical utility beyond what is already achievable and less prone to security flaws with bitcoin. There just doesn't seem to be much useful code that can come out of "money as variables in a program" since just about everything related to how humans intend to distribute money hinges on the facts of the real world for which the program must rely on humans to input.
