Are the alchemists of finance brewing another bubble even as we're struggling to escape the brutal aftermath of the last one in real estate? The frothy signs of a tech bubble are hard to miss.

INTERVIEW: No Bubble for Tech Stocks

Take Apple's stock. The world's most valuable company sports a market capitalization of some $530 billion, with its stock in the $530-a-share range (down from a peak of $636 on April 9, 2012). Apple's stock is up a dizzying 334% since the first iPhone was sold in June 2007, and it's up 126% since the iPad went on sale in April 2010. Research analysts, such as Gene Munster, of the brokerage firm Piper Jaffray, are racing to predict when the stock will go to $1,000 a share, a price that would push Apple's stock market value to more than $1 trillion.

The bubble-in-the-making murmur from Silicon Valley to Wall Street isn't just about Apple. Look at Facebook. It bought Instagram -- a two-year-old photo-sharing application with 30 million users, a dozen employees and no revenue -- for $1 billion. And Facebook's pricing for its initial public offering puts the value of the social-media behemoth at $105 billion -- a stratospheric figure for a company with $4 billion in revenue last year and an estimated $6-plus billion this year. The tech-laden Nasdaq Composite index is up 126% since hitting its low in March 2009. Standard & Poor’s 500-stock index has gained 105% over the same time period.

Shades of the dot-com era? Not so fast. At most, we're watching "bubblettes" forming.And while it may sound heretical, we should all hope the bubblettes eventually transform themselves into a balloon that buoys the overall economy. The unleashed animal spirits of speculative investment in high-tech would invigorate business activity far faster than anyone could reasonably expect from the dreadful economy of the past five years.

Yes, valuations are on the rise, especially for the Silicon Valley-based, consumer-oriented, social-media and advertising-supported sides of the high-tech market. But investors seem less dazzled elsewhere in the tech universe, including with regard to firms with more of a business-to-business focus. Most telling, it's hard to find signs of widespread delusion, the mass madness of the investing crowd, a speculative frenzy among ordinary investors and Wall Street professionals. "You can't have a bubble absent widespread, intense belief," said Silicon Valley serial entrepreneur Peter Thiel in a lecture at Stanford University in April.

He's right, of course. What's striking is how subdued the attitude is toward high-tech innovation outside of Silicon Valley. A major reason is gnawing doubts about the economic returns from the current generation of innovations, from the Internet to smart phones to social media. Economists such as George Mason University's Tyler Cowen, author of the e-book The Great Stagnation, argue that the economic gains from the current generation of innovations pale next to the transformative inventions of the late 19th to mid 20th centuries. Electricity, the automobile, the telephone, radio and other technological advances of that era truly transformed everyday life and the economy.

Alas, periods of major technological innovation also usually end up stoking speculative frenzies. Investors become increasingly optimistic that the new technologies will boost future economic growth. Managers realize that they need to adopt the new technologies, overhaul their organizations, experiment with different business models, and climb up a steep learning curve until productivity and competitiveness improve. The possibility of hitting it big attracts more brainpower and capital to the economy's technological frontier. Sure, plenty of harebrained schemes get funded, such as Webvan (e-commerce), Boo.com (online retailer), and E-toys (online toy retailer) during the dot-com frenzy. But plenty of durable companies get funded, too, such as Amazon.com, eBay and Google.

The strong relationship between major technological innovations and investment bubbles holds for many critical episodes in economic history, from the railroads in the 19th century to the Internet in the 20th century. "The fundamental impulse that sets and keeps the capitalist engine in motion comes from the new consumers, goods, the new methods of production or transportation, the new markets, the new forms of industrial organization that capitalist enterprise creates," wrote economist Joseph Schumpeter, a towering intellect with few peers in understanding innovation and capitalism.

I worry that we may be underestimating how much technological dynamism is being unleashed in the U.S. economy. Facebook and the iPad are the most visible symbols of the digital economy. But there's much going on beneath the surface of the economy, out of sight for most of us.

Since the Great Recession ended, business-equipment investment has risen to an all-time high, and much of it involves big data, vast digital networks and increasingly sophisticated software. "Digitization, in other words, is not a single project providing one-time benefits," wrote Eric Brynjolfsson and Andrew McAfee, director and principal research scientist, respectively, at the MIT Center for Digital Business. "Instead, it's an ongoing process of creative destruction; innovators use both new and established technologies to make deep changes at the level of the task, the job, the process -- and even the organization itself."

The scholars believe we're at the moment when digital innovation and organizational overhauls are starting to feed off and reinforce one another. Let's hope they're right.
