The construction of a new conventional wisdom is a wondrous feat. Seemingly, in the middle of the night, a new truth emerges that is impregnable, monolithic and unassailable, and it rises upon a landscape scattered with the rubble of previous conventional wisdoms. The newest "truth" is what appeared this week on the cover of The Economist: "The new tech bubble." But it's not just the Economist, which does wrestle with some of the complexities of bubble creation. The Economist, in fact, comes a little late to this parlor game. The notion that there's a new tech bubble -- inflated valuations from social media wunderkinds like Facebook, Twitter, Groupon and LinkedIn to the nosebleed-high $8.5 billion Microsoft paid to grab Skype -- has been a blogospheric meme and has recently graced, as if by dictation from above, nearly every major newspaper.
But is it true? Are these ballooning valuations for a handful of tech startups, mostly in social media, a reprise of the dot-com bust of 2001, or for that matter, the mortgage bubble and meltdown? How strong is the evidence? Are their divergences from those previous bubbles, which of course we can only confirm as bubbles because they burst? And the key question really: Why do we believe that we can call this inflation of tech valuations a bubble, when we've been so wrong, so regularly, in the past? What does it say about the power of the media to do anything about it? And what do we really mean when we say there's a bubble brewing?
