What's wrong with something that's decades old?
In the case of shells, not benefitting from the extra decades of experience. There are some horrible things that you can do with Bash just by mistyping a single character or using the wrong type of quotes or failing to appreciate how something will expand in some edge case. This is not a desirable property for an environment that people use after being paged at 4am, while their employer is losing $XXX,000/minute because something critical is down, and where the half-asleep operator is one short command away from deleting the universe without so much as a confirmation prompt.
