I think people who haven't worked on problems like this have much higher expectations than people who have.

If you have worked on problems like this, you're very happy to converge on the same state and have no expectation that multiple concurrent editors will be happy with the result. Or even that one of them will be happy with the result.

You wouldn't use this in a situation like version control where you have to certify a state as being acceptable to one or multiple users.
