YOU may have conceived the idea that drones are bad things.
They're used in wars, which by and large aren't good, and they seem crafty.
Drones are unmanned airborne spotters that pinpoint the whereabouts of the enemy or, in the case of the US military, one's allies, so that you can then attack them.
We're all ambivalent about this sort of thing. On the one hand, if in future all wars can be fought by robots, then fire away, you schmucks. One day, the robots may rise against us, but I'm far too busy to worry about that right now.
On the other hand, we seem to be getting further and further away from the idea of war as a fair fight, which it has only ever been in my imagination. Cut the cake of battle which way you like, it was always more noble to pit two lots of martial artists against each other, than it was to fire, first stones, then arrows, then grenades, then bombs, then missiles. Projectiles were always the coward's weapon of choice.
However, nothing is all bad, except maybe the Treaty of Union, and in the case of drones, a good use has been found for them. Paul Watson's heroic anti-whaling fleet is now deploying them to track down evil Japanese whalers, who are then confronted directly in a manly manner.
Like big tellies and computers, drones are coming down in price all the time, and you can pick one up for £500 now. That said, Watson's Sea Shepherd Conservation Society is using a state-of-yon-art £10,000 model, provided by US environmental company, Bayshore Recycling.
Watson says his eye-in-the-sky "makes it much harder for the whaling fleet to escape". That's why, in that sense, drones are definitely a good thing.
