"Amen. Ships, tracked vehicles and stationary artillery are as obsolete as the sling.
It is almost certain that twenty years from now wars will be fought by robots or humans behind screens.
There will be no more pilots.
The navy fleet will be no more than subs and that too should be a dangerous occupation."

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...

With Pearl Harbor the battleship, which had a hayday of some forty years, was made obsolete.
This world is turning more rapidly month by month. The battle for Ukraine should provide myriad lessons to be learned; however, much of what I wrote previously should have been realized a decade ago.
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.
