Mysterio has utilized drones on occasion in the comics. They are often part of his elaborate plans and illusions to deceive and confound his opponents.
Yes, they are. As of now, the concept of 'killer drones' that we often see in science fiction movies and books remains mostly in the realm of imagination. The technology and ethical implications involved in creating fully autonomous 'killer drones' are far from being realized on a large scale in the real world.
Because the technology for fully autonomous killing machines is not here yet. Drones today need human operation for most functions related to any kind of combat or dangerous tasks.
Well, drones provide a fresh viewpoint. You can program them to follow specific routes for a planned story, or simply let them fly freely to capture unexpected moments that could fit into a story. The high-quality footage they capture adds a visually captivating element.
Drones first emerged in science fiction back in the 1950s or so. They were often depicted as futuristic devices used for various purposes in imagined worlds.
The Octopus Murders is most likely fiction. This kind of title indicates a story crafted from the author's imagination rather than being a factual account of real events.
