I liked this piece, though I can't say it has matched my experience of updating.

Most of the beneficial paradigm-shifts I've experienced have taken a long time. The basis of my old belief system corrodes; a single precept is investigated and discarded, such that it isn't missed for long. Another precept is replaced as the flora inches closer. Months later, I stand in the ruins of the old civilization, a bit awed at the magnitude of the change - but fully able to track its progression, and ready to move on.

The more dramatic paradigm-shifts have been characterized not by discomfort at the loss of an old idea, but by awe at the beauty of the new idea - perhaps a sign that those shifts were a result of zealotry instead of rational change.
