Mainframe technology is obsolete. This is why it is not taught anymore. Notice it is only promoted by IBM. Big companies run mainframes becuase new technologies are radically different. COBOL has very little in common with any language developed in the last 10 years. There is a reason for this. COBOL sucks. CS as with every other science, has actually progressed in the last decade. Big companies reason upgrading is to dangerous to the status quo, after all, the changes may not work right at first. The wiser people at Universities realized not upgrading is too dangerous. Staying with the same old thing simlpy because it works causes stagnation. Smaller, more flexible companies will replace the large companies that don't eliminate the mainframes. Large companies that replace the mainframes stand a chance at changing their 10+ year old processes and competing in the next decade. Those that don't won't even be able to pay the pension for the mainframe retirees.
