In the 1920s, after the development and successful use of combat aircraft, many theorized that wars would be largely fought in the air at the expense of ground and sea forces.
In the 1950s, after the development and successful use of the atomic bomb, many theorized that wars would be largely fought with atomic weapons at the expense of conventional weapons and force structure.
In the 1990s. after the successful use of precision munitions in Iraq, many (especially in the West) theorized that wars would be largely fought by small, nimble forces with precision guided munitions, at the expense of mass.
In the 2020s, after the successful use of cheap drones and FPVs in Ukraine, some theorize that wars will be entirely dominated by cheap drones at the expense of anything with a budget over $100 or whatever.
All of these theories are interesting to talk about in their own right, but my kind of snarky point is that this idea that some new technology is going to completely upend military affairs is nothing new. 90% of the time, the new tech simply finds its own niche and we realize that we still need the shit that it was going to upend.
