I think the wording in Randall's comic was very deliberate. "Nothing is ever foolproof", "Nearly incapable". Software engineers can absolutely reach those standards. But we also understand the threat model well enough that to us, "almost foolproof" is equivalent to "totally broken". We understand that there are smart saboteurs looking to attack our systems, we understand that our software is only one link in a very susceptible chain, and we understand that they know our almost foolproof system is totally broken.
