This is a difficult question to answer definitively because "deep tech" can mean different things to different people. Generally speaking, deep tech refers to technology that is based on groundbreaking scientific research and has the potential to create large-scale investment and social impact.
Drone technology definitely falls into this category. Drones are based on years of research in the fields of robotics, computer vision, and artificial intelligence. They have the potential to revolutionize the way we live and work, and they are already having a major impact in a number of industries.
So, in conclusion, I would say that drone technology is definitely deep tech.
