I think this is binary categorical thinking. In the real world, safety systems (even in domains like aviation or nuclear power) are never foolproof-the point is you reduce the probability of failure to an acceptable level given the costs of doing so and the potential consequences of that failure
And there is the risk people say “there is no foolproof solution, so I’m not going to invest in probabilistic countermeasures” - which would sound like utter madness to a bank’s antifraud department, but for some reason a lot of people seem to think it isn’t when it comes to AI
