Mark Twain said that. There are variations on the quote, but they all say the same thing: "I'm still alive!!!'
I work with mainframe computers. For a long time, people have said the mainframe is dead. In 1994, Client Server Today magazine said "The mainframe is dead. It's time to give it a decent burial and move on."
In 1991, Stewart Alsop said "I predict that the last mainframe will be unplugged on March 15, 1996."
But a google search of "mainframe" will show that the mainframe is alive and well today and if you search "mainframe jobs", you'll get lots of hits with places to go look for employment. And if you look for "mainframe university", you'll see colleges are teaching about the mainframe too.
So who cares about the mainframe? Well, it seems to me that the same story applies to lots of things, and I just wanted to remind one of my readers in particular and hope she uses the analogy.
