Over the years, we have learned that there are many reasons that pilots take to the sky. Some do it for the sheer pleasure of controlling an aircraft, others want to see the world from above and capture great photos, while others fly for work, carefully surveying a job site or working to save lives. It is true that most drones can handle most tasks, but as with anything, to be good at everything means you're a master of nothing - simply put, there are specialized machines for certain tasks, and there are full-featured drones that happen to do one thing better than another. A camera drone would not be good on a drone race track, and a race drone would be pretty horrible at surveying a job site.
