If you're going to make a generalization, I think recursion is fine, efficient, and rarely dangerous. There may be use cases where it's insecure or has performance concerns, but those are the exception. Most of the time, it's fine. We don't generally tell programmers that loops are naive, often dangerous, and risk locking up the program. They certainly can, but most just... don't. Just like loops, recursion can make code much simpler to write, read, and maintain. Every modern language under the sun supports it for very good reasons. Use it.
