Nowadays, more and more drones are being used in wars around the world.
Drones can fly far to attack targets and do not need a human pilot, so no soldiers get hurt.
Recently, Ukraine used many drones to attack Russian aircraft, which made people start worrying about the development of drone technology.
Drones can now not only take photos but also attack and scout.
In the future, there might be drones like small birds that secretly observe or attack people.
Many people worry that if only rich people and powerful countries control these drones, ordinary people will become more vulnerable.
Our freedom and safety might be threatened because drones can monitor us at any time.
Technology makes life more convenient but also brings new problems.
We should think about how to use technology to protect everyone, not to harm others.
