In this article,AN INTERMEDIA WITH 2 BILLION SCREENS PEERING INTO IT Kevin Kelly, describes the way in which the Internet has affected our "knowledge." I have highlighted sentences that capture the spirit of his thinking.
"But my knowledge is now more fragile. For every accepted piece of knowledge I find, there is within easy reach someone who challenges the fact. Every fact has its anti-fact. The Internet's extreme hyperlinking highlights those anti-facts as brightly as the facts. Some anti-facts are silly, some borderline, and some valid. You can't rely on experts to sort them out because for every expert there is an equal and countervailing anti-expert. Thus anything I learn is subject to erosion by these ubiquitous anti-factors.
My certainty about anything has decreased. Rather than importing authority, I am reduced to creating my own certainty — not just about things I care about — but about anything I touch, including areas about which I can't possibly have any direct knowledge . That means that in general I assume more and more that what I know is wrong. We might consider this state perfect for science but it also means that I am more likely to have my mind changed for incorrect reasons. Nonetheless, the embrace of uncertainty is one way my thinking has changed.Uncertainty is a kind of liquidity. I think my thinking has become more liquid. It is less fixed, as text in a book might be, and more fluid, as say text in Wikipedia might be. My opinions shift more. My interests rise and fall more quickly. I am less interested in Truth, with a capital T, and more interested in truths, plural. I feel the subjective has an important role in assembling the objective from many data points. The incremental plodding progress of imperfect science seems the only way to know anything."
