I have a feeling, looking back, that the birth of weaponized drones will be far worse for our world than the invention of the nuclear bomb. they're already being used domestically in the United States by law enforcement, which raises some pretty disturbing prospects. and now other countries (e.g. China) are creating drones at a breakneck pace....
tl;dr<p><pre><code> Big drones have little drones,
upon their backs to launch them
And little drones have lesser drones
An so on ad infinitum
And the great drones, themselves, in turn
Have greater drones to go on;
While these again have greater still,
And greater still, and so on.</code></pre>
I can't help but imagine that whoever has the bad luck of fighting against against the drones and robots of US will feel much like in Terminator 3, except the drones and robots won't attack on their own, but will be manned or sent by the US military instead.
