Micheal Hayden during a Blackhat keynote likened 'cyber' to a new domain (like air, land, sea), that's universally like early WWI with open fields of men with no defenses being mowed down by attackers' machine guns.

As an aside, it probably would have been smarter to make Cyber Command it's own branch rather than the Space Force. Space operations are basically figured out with the Air Force taking most of the lead. Cyber Command is apparently a cluster fuck of separate command structures all vying for power. Spending the time making a Space Force always seemed like a 20th century move in a 21st century env.

Yeah, it feels like the "golden age" in some way - there's lots of developments available on both sides.

I expect things will "calm down" over the next fifty years as defense-in-depth and security become ingrained into how we work. Compare a "modern network" with the first ARPANET.
