COBOL/CICS was supplanted mostly because mainframes were supplanted due to smaller organizations, that wanted to use computer technology, not being able to afford a mainframe. Companies could lease time. But I don't remember it being the norm. Mini's and then Unix systems allowed us to develop systems with newer technology. Wintel systems expanded it further. My point is that the new technologies came about via need: it allowed more people to utilize computer technology to solve problems. As needs change, we'll continue to see an evolution of technology to meet the needs.
