Biohacking: “The activity of exploiting genetic material experimentally without regard to accepted ethical standards.” Some hacks involve putting a small magnet in your finger, some go much farther, one man even gave himself night-vision.
Euthanasia: “The act or practice of killing or permitting the death of hopelessly sick or injured individuals (such as persons or domestic animals) in a relatively painless way for reasons of mercy.” This is a highly controversial topic, assisted suicide is illegal in most countries.
Autonomous vehicles: Vehicles capable of driving themselves have become a topic of road safety lawmaking since the first inception of the design. One of the main reasons this is a concern is because the car might face what is called the trolley dilemma. In the event of an accident or loss of control, the vehicle might have to decide which pedestrians survive, and which die.
