There are big deadly weapons to worry about, such as weapons of mass destruction that come on an ICBM or even in a suitcase bomb to frightening armies of massive killer robots.
And then there are small nanobot weapons to worry about--which don't sound like much, but they could be the ultimate killer machines.
About 10 nanometers make up the width of a human hair, so we are talking about microscopic or bug size weaponized drones.
Nanobots can be manufactured or scarily can be self-replicating.
They can fly alone or in massive swarms.
They can surreptitiously enter/exit and carry out their missions virtually undetected.
Whether surveillance or delivering a mini-nuke or a toxin.
Nanobots could function like a biological weapon killing millions--targeted or indiscriminately.
Cambridge University forecasts a 5% chance that nanotech weapons could cause a human extinction level event by the year 2,100.
Soon wars will not be fought by people any longer--by rather by robots and nanobots.
People are too fragile for fighting and war against ruggedized and militarized bots that are designed for one purpose only...to kill, kill, kill.
Terminators are coming--from massive to nanoscale--and mere humans will be dogmeat to these killing machines.
Add in a cyber warfare component that will turn off 21st century civilization leaving us to fend as if we were back in the stone ages, and overpopulation is the last and funniest joke any of us will ever tell.
