In the age of Web 2.0, authoritative expertise is slowly waning. The layman reasserts herself as a fount of collective mob "wisdom". Information - unsorted, raw, sometimes wrong - substitutes for structured, meaningful knowledge. Gatekeepers - intellectuals, academics, scientists, and editors, publishers, record companies, studios - are summarily and rudely dispensed with. Crowdsourcing (user-generated content, aggregated for commercial ends by online providers) replaces single authorship.

A confluence of trends conspired to bring about these ominous developments:

1. An increasingly narcissistic culture that encourages self-absorption, haughtiness, defiance of authority, a sense of entitlement to special treatment and omniscience, incommensurate with actual achievements. Narcissistic and vain Internet users feel that they are superior and reject all claims to expertise by trained professionals.

2. The emergence of technologies that remove all barriers to entry and allow equal rights and powers to all users, regardless of their qualifications, knowledge, or skills: wikis (the most egregious manifestation of which is the Wikipedia), search engines (Google), blogging (that is rapidly supplanting professionally-written media), and mobiles (cell) phones equipped with cameras for ersatz documentation and photojournalism. Disintermediation rendered redundant all brokers, intermediaries, and gatekeepers of knowledge and quality of content.

3. A series of species-threatening debacles by scientists and experts who collaborated with the darkest, vilest, and most evil regimes humanity has ever produced. This sell-out compromised their moral authority and standing. The common folk began not only to question their ethical credentials and claim to intellectual leadership, but also to paranoidally suspect their motives and actions, supervise, and restrict them. Spates of scandals by scientists who falsified lab reports and intellectuals who plagiarized earlier works did nothing to improve the image of academe and its denizens.

4. By its very nature, science as a discipline and, more particularly, scientific theories, aspire to discover the "true " and "real", but are doomed to never get there. Indeed, unlike religion, for instance, science claims no absolutes and proudly confesses to being merely asymptotic to the Truth. In medicine, physics, and biology, today's knowledge is tomorrow's refuse. Yet, in this day and age of maximal uncertainty, minimal personal safety, raging epidemics, culture shocks and kaleidoscopic technological change, people need assurances and seek immutables.

Inevitably, this gave rise to a host of occult and esoteric "sciences", branches of "knowledge", and practices, including the fervid observance of religious fundamentalist rites and edicts. These offered alternative models of the Universe, replete with parent-figures, predictability, and primitive rituals of self-defense in an essentially hostile world. As functional literacy crumbled and people's intellectual diet shifted from books to reality TV, sitcoms, and soap operas, the old-new disciplines offer instant gratification that requires little by way of cerebral exertion and critical faculties.

Moreover, scientific theories are now considered as mere "opinions" to be either "believed" or "disbelieved", but no longer proved, or, rather falsified. In his novel, "Exit Ghost", Philip Roth puts this telling exclamation in the mouth of the protagonist, Richard Kliman: "(T)hese are people who don't believe in knowledge".

The Internet tapped into this need to "plug and play" with little or no training and preparation. Its architecture is open, its technologies basic and "user-friendly", its users largely anonymous, its code of conduct (Netiquette) flexible and tolerant, and the "freedoms" it espouses are anarchic and indiscriminate.

The first half of the 20th century was widely thought to be the terrible culmination of Enlightenment rationalism. Hence its recent worrisome retreat . Moral and knowledge relativism (e.g., deconstruction) took over. Technology obliged and hordes of "users" applied it to gnaw at the edifice of three centuries of Western civilization as we know it.
