Paraphrasing (8th paragraph)

Text

The next expansion may well look different from the last one, with a new complement of companies leading the charge. Pharmaceutical and biotech companies are likely to expand rapidly, riding the wave of innovation that results from the unraveling of the human genome. As for info tech, expect a mixed bag. It’s hard to see who’s going to sizzle by making slightly faster routers, or stringing yet more optical fibers across prairies and oceans. What consumers and businesses want now are systems that produce immediate, concrete benefits. Computing on demand, for instance, is supposed to make computing as easy as turning on a water tap. Instead of running its own complicated info-tech shop, a business pays by the month to use hardware and software maintained by an outside specialist. A promising new generation of collaborative software from companies such as MatrixOne, Agile Software, and logistics.com eliminates bottlenecks in supply chains through information sharing. And wireless still holds promise: Pretty soon, experts say, cell phones and the Internet will go together like peanut butter and jelly.
