請依下文回答第 37 題至第 41 題: American technology companies once led the way in developing innovative products and services. But today
many big tech firms seem to have lost their innovation mojo. In 1970, IBM 37 the world’s first interchangeable
family of computers, the revolutionary System/360 mainframes. It was a 38 bet on innovation that Fortune
magazine at the time called “IBM’s $5 billion gamble.” In today’s money, that’s the 39 of a $40 billion wager on
innovation—one that incidentally required IBM to cannibalize all its existing revenue-producing product lines. But the
bet worked. The System/360 line quickly became the 40 mainframe in the market and the de facto industry
standard, ensuring IBM’s supremacy in the industry for a generation to come. Back then, it was an axiom of business
leadership that today’s investments in R&D lead to tomorrow’s 41 and profits. But today, this ancient wisdom is
in danger of being lost.
