Are you saying superconducting railguns could possibly cause problems?!?

They could only cause problems solvable by more superconducting railguns, so they're a net zero at worst.

If the projectile is ferromagnetic, or potentially even just diamagnetic, a defense system involving shaped ultra-high intensity magnetic fields becomes conceivable.

When you activate the city shield, all your buildings become projectiles.

I believe ultrafast capacitors for high-energy lasers would be possible. Most likely some type of laser gatling gun configuration.

Hopefully they don't cause solar system wide loss of consciousness events.
