We could have left everything in COBOL and IBM OS and just added a GUI and internet connections. Just think how much time, money and resources were wasted converting everything. And then most of it didn't work very well on PCs (didn't scale well and the "security" was horrible). The typical shop I worked in spent 1/3 of their resources on maintaining current apps and 2/3 on converting and installing new languages and OS and many were dismal failures. IBM already was building relational databases, etc.
