"Bionic Bird benefits from strict quality controls that are so rigorous that each bird is built like a prototype." ....um, what?

Ehhh.... Reminds me of the story about when the Soviets were cloning the B-29 to make the Tu-4. Supposedly Stalin ordered an exact copy of the American bomber, and so the copies were made exact down to the bullet holes.

What was Stalin's reaction?

Don't know, nobody lived to tell about it.

Bullet holes, brown M&Ms, it is all about attention to detail.

I think they might not have a native English speaker. Check out the title of this official video. https://www.youtube.com/watch?v=gFS2JWUkdvw

A flawed prototype does no one good. Could imply that the specs are high too.

Begun, the drone war has.

The ancient profession of netmaking will be completely relevant to high tech. Science fiction writers give up.

Or you know, swarm the skies with tons of small drones making it impossible for the police to catch them all at once.

Or bring scissors to cut the net?

Or drones with blades that cut as they turn.

None of these countermeasures will matter after the Tokyo police start injecting stomach acids that digest the victim drones from the inside out.
