Venture capitalists' taste for risk has changed for a number of reasons, including the difficulty of taking tech companies public or selling them for lucrative paydays. The result is that venture firms are putting much less money into tech startups than in the past, and the money they do invest goes into less expensive, less risky deals, including social networking startups such as Facebook, Twitter, Yelp, and Digg.These so-called Web 2.0 companies are creating exciting new forms of socialization, information sharing, and entertainment. But some of the Valley's old guard are skeptical they'll grow big and important enough to deliver sizable productivity gains for business and the nation or to produce an upswell in new core technologies.Today's startups "give us refinements, not breakthroughs," says Andy Grove, former chief executive of Intel (INTC).
For more than 40 years, Silicon Valley has been the world's most prolific laboratory for information technology innovation. But Estrin, Grove, and others are growing concerned that the vitality of the Valley, and, indeed, that of the entire U.S. tech industry, is at risk.
New technologies may also end up eclipsing the old. Semiconductors, for example, laid the foundation for technology improvements in the past, but there may be more important advancements elsewhere in the future. Ken Lawler, a Valley partner with the venture capital firm Battery Ventures, points to new developments in biotech, solar power, and other green technologies. "Innovation is still alive and well," he says. "It's in new areas."
