Mainframe computing was the cornerstone of computing and was used for all sorts of tasks from military control to word processing. It had proven to be cost-effective, efficient, and fit for most tasks. However, 20 years back, personal computing took the computing world by storm and has now replaced mainframe computing in all walks of life, enjoying the same success that mainframe computing once did.
Based on the sequence of events above, which of the following can be properly concluded?
A. Technological innovations have a history of disrupting dominant market force and replacing it with the next wave.
B. Every computing technology, however successful and cost-effective, will eventually be disrupted
C. It is not necessary that a computing technology that has been a dominant force in one era will continue to dominate the computing landscape forever.
D. A dominant technology has a higher chance of being disrupted than a technology that is not as dominant.
E. In the technology world, if an emerging technology is to gain a foothold, it must disrupt a dominant technology.
