Simply nuking the shit out of everything wouldn’t really make for an interesting story.
It did for the Killing Star. Not nukes, but R-bombs which are probably the most insane WMD-s and unlike strangelet bombs actually feasible even at our current tech level. All you need is a light-sail and a big-ass solar-powered laser.
But, yeah, for dune:
- Drop an active shield generator on your enemy position
- Shoot it with a laser
- Hilarity ensues
How does one find out what chips are in what USB sticks? Manufacturers don’t make this information available. At best you just find read and write speeds, usually just the max possible read speed and nothing else.
