"common sense has been undermined by implausible technological feats."

Margaret Morse's statement is bluntly correct. From the act of identity theft to surveillance equipment or cell phones... technology has created avenues of interaction on levels only dreamt of a hundred years ago. This new culture being introduced through new technology and media is radically changing our social "common sense."
As these advances make human life more instantly gratifying they are contradicting the classical common sense which is tribalistic in nature - love thy neighbor etc...
the new technology is individualizing everday life. What once was a society relying on the other members of that society, the new social sense is, in a way, blind. As humanity is removed from the roots of this technological history they rely on this new technology to get them through life and not enough on humanity's natural strengths. I believe this is the classical common sense Morse refers to. With this dependance on technology in everyday life, humans are reshaping their existence from a being at one with nature to a life in a contrived shell that shields us from nature's perils.
