I'll assume you know about Dave Plummer. He addresses the
Why Are Mainframes Still Sold question in ~25 mostly dense
minutes at https://www.youtube.com/watch?v=ouAG4vXFORc --
this is information with which all serious IT pros should
have some level of familiarity. I particularly like the
footage of testing for operational continuity during
earthquakes (as well as surviving shipment from the factory
to the customer).
