Just remember French writer Jules Verne and his bunch of fantastic ideas described in his novels. Most of them are real now. One day Czech writer Karel Capek has used the word “robot” for the first time and now we have dosens of robots of different types. And at last (wow, I’ve managed!) let us think of James Bond who has used a pack of devices that were absolutely unreal for the time the book had been written. Now everybody could buy a spy earpiece device or find a pen that could sign a contract and be used like a gun after that.
It is clear that the main two engines of the technical progress are business and government military sector. And in fact that two forces are working together to bring you the things you have used to. E.g. Internet has been discovered by militaries for their own needs. And after that it has fallen into business hands that allowed it to improve to its modern state.
So when you see a new spy device in Bond’s hands it is always a good idea to think a little where it could be used in civil life. Maybe you manage to discover something that could be useful for many and bring you fantastic profit.
“I have a dream…” that all of the readers shall dream of strange application of usual devices…
