Larry, I'll let others provide summaries and links, however, I'd say mainframes are definitely here to stay. IBM and its operating systems may have been around for many years, but IBM has done an excellent job of modernizing both hardware and software. When you invoke some software, whether by mouse click, enter key, or some other means, somewhere some software must run on some hardware. When milliseconds count, you cannot beat IBM z/OS technology. And, no, I am not an IBMer.
However, the last production site I worked at (now a software developer for MVS/Quickref), milliseconds counted. Our management objective was response times of 0.5 seconds or less. We ran 23M transactions per day, using z/OS, CICS, Db2, MQ and did so in an average of 0.39 seconds per transaction. Response time on a web frontend that initiated that transaction might be substantially greater, but it was not the application doing the work that was slow. I am unaware of any other platform capable of giving that type of response. These were not simple applications. Most, if not all, banking, insurance, and other financial applications run on IBM z/OS. I, personally, do not believe it is going anywhere anytime soon. It is a shame that most educational institutions have abandoned teaching mainframe languages and technologies.
