Sure... sure they are obsolete.
And when I was a boy I watched the Jetsons cartoons where people flew around in their own personal jet-cars, and we expected to see colonies on Mars in a few years.
Of course there's no doubt technology is changing fast, but some things don't change as much as you might suppose...

Parenthetically, the Navy is sending ships less than ten years old to the graveyard because they are obsolete. And the Pentagon at this moment is trying to determine the future role of the U.S. Marine Corps. And the US airlines are hunting for pilots because the forces are not training as many pilots as they once did. In other words obsolescence in the military is everywhere apparent.
