Self-Avoidance Pros and Cons

With new technologies being developed everyday, one of the more interesting ones right now for the drone communitty is the ability for drones to sense and avoid obsticals. 

The newest DJI drones such as the Phantom 4, Mavic and Spark all use this new ability, but I ask the question: is it "really" useful?

The answer depends on how you use your drone. For beginners, hobbyists and drones operating beyond visual range / high traffic areas, the answer would obviously be yes, it can help you a lot, and prevent damage to your drone, and other persons or property. 

Self avoidance begins to become a hinderance when we move into the professional spectrum such as commercial drone usage and drone racing. Out of personal experience, I need to be able to fly me drone close to trees and other obstacles. This technology would be a put off for me due to taking away a lot of my "canvas". The same would be for drone racing as it would limit how close you can fly near the course and possibly other aircraft. 

Obsticale avoidance is still a new technology that we see with drones, self-driving cars and other new technologies, but for now, I feel it is safe to say the professional user may want to currently avoid due to it limiting one's airspace, yet it is a great asset for new fliers and the general public!
