单选题A huge population of red fire ants has bedeviled Texas farmers for years. By some estimates the insectscost state businesses close to $1 billion a year due to crop and machinery destruction. Killing the ants and their nests has not proven easy. Texas A＆M researchers have discovered that the phorid fly from South America will lay eggs on the red fire ants and the maggots which are hatched eat away at the ant's brains, eventually causing their heads to fall off. Someone at the university was willing to underwrite the work to solve a problem. That investment was almost certainly much less than the $1 billion a year that fire ants cost businesses in the state. A recession does not stop advancements in technology. It just makes companies so frightened of risk that they choose not to make the investment in the red fire ant projects. In the last week, the two most successful technology companies in the world, IBM and Google have announced major new products. IBM released "stream computing" applications that allow businesses to look at and analyze huge amounts of data in real time. The most important product of Google allows the company's customers to take very large amounts of search data and organize it into spreadsheets. These are developments that will probably help the firms take business away from their competitors. The shares of Google and IBM have handily outperformed those of all the other large tech companies based in the U. S. such as Hewlett Packard (HPQ), Microsoft (MSFT), Cisco (CSCO), and Oracle (ORCL). Each of the companies is blessed with substantial earnings and technology staffs in the tens of thousands. But the firms are not all viewed the same, at least by investors who trade tens of millions of their shares each day. In most ways, IBM and Google are not like one another at all. IBM makes its money selling expensive hardware, client services, and software to companies, most of which are very large, and to governments. Google has millions of customers who pay nothing to use its services. It has millions of advertisers who spend money to reach people who look at search results and most of these marketers are very small. What the companies do have in common is a willingness to take risks, probably risks with long odds in order to launch new products. These products may be failures, but they are well enough researched and designed that they have a good chance of keeping IBM and Google ahead of the competition even if that does not immediately involve significant new revenue. The red fire ant problem never goes away. Unsolved problems in every industry cost companies money. Sometimes companies do not even know that their problems can be solved. The phorid fly is an obscure species. So is software that can analyze huge amounts of data in real time.
