Earlier quoted context omitted.
That we still find new structures within our own bodies should be deeply troubling to anyone in the medical sciences. I for one would be deeply ashamed if I suddenly found that bytes had a ninth bit we never suspected was there in the first place.
Of course it would be embarrassing to discover a ninth bit; humans invented, created, and placed the other 8 bits, along with the entire computing infrastructure around them. Humans did not invent the human body, so it's not embarrassing to discover something new--it's exciting. That's the whole point of science. Medical researchers certainly know that they still have a ton to learn about the human body.
Humans did, but not you or me. What if they lied to us? What if we believed in those lies and never checked? ;-)
