The point being made here is that you can be infinitely specific and still run into unexpected failures. If you're going to claim there is a way out of that you are either very young of just straight up lying.
We're talking about Erlang here which, to my knowledge, is the only mainstream-ish general-purpose programming language that was developed to solve an actual business problem. To be that guy that quotes a relatively well-known quip that maybe you've already heard, the unofficial tagline was: "Remember in the 90s when your phone company would call you up and say that you can't use your phone for a few hours for 'planned maintenance'? Of course you don't... and that's tanks to Erlang."
That was accomplished because you can just specify the happy path, deal with well-known exceptions (are they really "exceptional" at this point?), and otherwise just turn it off and on again, as we all do. And, not to start a flame war, but it's a dynamically typed language to boot!
