The collapse of Wall Street may help make computer science and IT careers attractive to students who abandoned these fields in droves after the pop of the last big bubble, the dot-com bust of 2001.

William Dally, chairman of the computer science department at Stanford University, said that for the last several years, he has watched some students interested in technology go into banking and finance because those fields could be more lucrative.

"Many thought they could make more money in hedge funds," Dally said. He said students are returning to computer science because they like the field and not because it can necessarily make them rich.

John Gallaugher, associate professor of information systems in the Carroll School of Management at Boston College, said he's already seeing a shift in student interest.

"Students have commented to me and written on their course wikis that they're considering changing from finance [majors], both based on the appeal of IS and concern over availability of finance jobs" in the future, Gallaugher said.

After the dot-com bust, computer science enrollments began declining, reaching a low of 8,021 last year from 14,185 in 2003-2004, according to the Computing Research Association (CRA) in Washington, which tracks year-over-year enrollment and graduate trends at 170 Ph.D.-granting institutions.

"Current economic conditions seem to impact the choice that students make in the majors they choose -- that has been true for computer science," said Jay Vegso, a CRA analyst who studies computer science enrollment trends. "Students who are now choosing majors might be looking for safer alternatives," he said, and IT may be a safer alternative.

The dot-com era was a wonderful time to be young, computer-savvy and in search of stock-option riches. Wall Street poured billions of dollars into hundreds of companies that were making little or no money. For instance, Webvan Group, a grocery delivery firm that was founded in 1997, had so much money that it bought a rival, HomeGrocer, in 2000 for US$1.2 billion in stock. Webvan ended in Chapter 11 bankruptcy in 2001.

If the dot-com meltdown wasn't enough, offshore outsourcing also scared away students from technology. In 2004, Carly Fiorina, then CEO of Hewlett-Packard, summed up the offshore trend this way: "There is no job that is America's God-given right anymore." Fiorina is now an adviser to Republican Sen. John McCain in his bid for the White House.

Today, companies are suffering from a shortage of technology professionals and baby boomer retirements will only add to the problem.
