But why? You're making the assumption that everyone using these things is trying to replace "average human". If you're just trying to solve an engineering problem, then "humans do this too" is not very helpful -- e.g. humans leak secrets all the time, but it would be quite strange to point that out in the comments on a paper outlining a new Specter attack. And if I were trying to use "average human" to solve such a problem, I would certainly have safeguards in place, using systems that we've developed and, over hundreds of years, shown to be effective.
