My understanding of that comment is that "a generally intelligent system" also applies to humans. Which can also be targeted by social engineering which those prompt attacks are. (as in, I won't be surprised if it is possible to put an adversarial human-targeted prompt in a document which some people will execute).

So, like with self-driving cars, while having fool-proof agents would be nice, agents being better than an average user would already be an improvement. Of course, blast radius from an agent might be larger, this should be taken into account.
