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.
I agree that stationary artillery is obsolete. I believe that ground warfare employed by Russia has not adapted to the high tech arena. However, I do not believe that surface ships are obsolete.
My hope is that Navy doctrine, strategies and tactics are being updated to reflect the high tech threat.
I believe that the scientists and engineers that design and develop high tech offensive weapons can also design and develop high tech defensive weapons capable of neutralizing the offensive weapons.
Suppose that the Space Command (founded under President Trump) has a primary mission of destroying or disabling all enemy satellites within 48 hours of a declaration of war. The enemy can't hit what they can't find.
If the surface navy ever becomes obsolete, then the army and marine corps can transfer to the Department of Homeland Security since they will have no way to get to the battle.
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...
