This reminds me of something I read the other day¹, the idea that complex fault tolerant systems tend to end up running with faults as a matter of course (and sheer probability). This elevates that notion to another level, get rid of the idea of operating without faults and maintain a low-level of faultiness artificially to ensure that resiliency to faults in the system is always working.
Reminds me of biology. It's always intrigued me that we often want to make computer systems as "good" as humans, and yet our acceptance of human faults is far higher than what we accept from computers. Any small part of a body may have some problems, but the body as a whole continues to function well. I wonder if this kind of design will become a trend?
We tolerate fewer faults from our computers because the underlying system is not complex enough to prevent those faults from affecting us in large ways. As you say, a small failing in the human body doesn't render the entire organism inert and useless; no, we can adapt our behavior during healing and move on. When a small fault occurs in your computer, it tends to have disastrous effects.
We will tolerate faults in our computer systems when then faults don't cost us our homework, our jobs, or our lives. And complexity is the only way to making that happen.
I, for one, welcome our new chaos-wielding overlord!
