This is a reason that I think we might be one of the first technological civilizations in the galaxy. If we still exist as a species in 100,000 years we will have undoubtedly spread to other star systems while broadcasting obvious techno signatures to any species with at least our current technology. 100,000 years is a blink of an eye in cosmological terms. If there were previous intelligent civilizations you would think that one of them would become space faring and we would have observed something unnatural by now.

The dark forest hypothesis is terrifying. Maybe one day being a violent, defensive nuclear species will pay off if some local bullies decide to try us.
