Virtualisation?

I listened with amazement to the talk on Virtualisation as if it's a new technology. Mainframes from the likes of IBM, ICL, Honeywell etc were doing this back in the early 70's. I was giving presentations with almost the same diagrams to describe virtual machine computer architecture in 1975. And yes we were emulating different hardware platforms on the same machine too (it was a common tool for transitioning from legacy systems). Then along came unix servers and people started to argue of the advantages of splitting the workload onto multiple servers to save costs. The latest thing now seems to be that the industry has rediscovered the mainframe!
What is it about the IT industry that each generation seems to believe that they have reinvented everything. Don't they get taught any history?
