The author raises the interesting point that if it's truly an exception, you're better off letting the system crash all together (especially in a webapp, where you're basically dropping a single request for a single user) -- and if it's an "expected exception", then you should be handling it directly.
I don't see how that reduces to "never use try/catch" though, since catching a specific exception (or types of exceptions) is a way of "handling it directly."
