Yes and no. Really, developed world have very stable laws, this is one of pillars of power.
So, new companies, like Uber, Apple (appstore), Microsoft (when created XBox), etc, sure have to create new infrastructure from scratch, because their new vision is their concurrent advantage.
But, for old businesses, like financial, energy, some others, most important to use all measures to cut transaction costs, and they achieve this by reusing old information infrastructure (not only this, but this is important part of equation). Unfortunately for old big businesses, their business models created when only mainframes could withstand their scale (clouds with micro- become mature enough, I think in 1990s; mini's just not considered as replacement of big machines), so big companies have large heritage on mainframes.
I know few cases, when large company move their infrastructure to cloud, but as I know, they mostly prefer to remain with old but reliable mainframes if possible.
At end of my speech I could add, I myself could be considered hunter from micro-world, who hunt for people who wish to switch (to micro and clouds), so I really know how much it cost :)
But to be honest, I feel romantic feelings to mainframes, as they are important part of history, I think we should save them for future generations.
