Yes, drones will ultimately become a booming commercial business. More and more is being done around the world with unmanned aircrafts. Be it as a weapon, intelligence gathering, or even surveillance and security on the border.. The need and demand is rising which is what is required to become a commodity in need.
Like any warfare-related equipment throughout history, drones will become a booming business. In fact, I'm sure they already are, it's just that they are such a distasteful subject that such a thing is not touted in the national and international communication. But think about it. They're being used. Poor civilians are experiencing the devastating effects. These drones are not being made in a castle in the sky. Someone is making money off their production and dissemination.
Drones will become a booming commercial business. It is only a matter of time. It is a way for a militarily to without risking the lives of its soldiers. Drones are very beneficial and I expect them to become very popular in the next few years. This could be the next way we fight wars.
Drones may be the future of military weaponry, but I don't think it's going to be a booming industry that will sweep the economy. It will be booming for certain people making money off of the military, but in the meantime I wouldn't say it's going to sweep the economy.
