  • Dan Dennett talked of "unthinking engineering" in his 2002 TED speech, quote:

    Yesterday, Amory Lovins spoke about "infectious repetitis." It was a term of abuse, in effect. This is unthinking engineering. Well, most of the cultural spread that goes on is not brilliant, new, out-of-the-box thinking; it's infectious repetitis.

    And we might as well try to have a theory of what's going on when that happens, so that we can understand the conditions of infection."
