Forget shopping. Soon you’ll download your new clothes

Augmented Reality

Downloadable, printable clothing may be coming to a closet near you. What started as designer Danit Peleg’s fashion school project turned into a collection of 3D-printed designs that have the strength and flexibility for everyday wear. “Fashion is a very physical thing,” she says. “I wonder what our world will look like when our clothes will be digital.”

The ethical dilemma of self-driving cars


Self-driving cars are already cruising the streets today. And while these cars will ultimately be safer and cleaner than their manual counterparts, they can’t completely avoid accidents altogether. How should the car be programmed if it encounters an unavoidable accident?

WATCH A VIDEO ABOUT the murky ethics of self-driving cars AND CHOOSE THE CORRECT ANSWERS.

2. In the second scenario, which option would follow the design principle to minimize harm?

A) The car swerves toward the motorcyclist with the helmet

B) The car does not swerve and stays in its lane

C) The car swerves toward the motorcyclist without the helmet

D) None of the above

3. If a robot car reacts exactly as a human would in a crash scenario, which would be true?

A) A random-number engine is needed, since some human actions are random

B) The same actions should result in the same legal consequences

C) None of the above

D) Impossible–the sensors on a robot car will enable it to avoid crashes

4. What other ethical dilemmas are mentioned here about autonomous cars?

A) Determining the value of your life versus the lives of others

B) Whether it should take a parking spot away from a human driver who’s looking for one

5. How are these thought experiments like science experiments?

A) They can safely recreate actual scenarios, without any risk of injury

B) They aren’t necessarily meant to recreate actual scenarios

C) They’re not alike–one involves lab equipment, and the other does not

D) None of the above

6. When an ethics judgement is needed, who should get to decide how robot cars are programmed: engineers/programmers, manufacturers/company executives, government, owner/occupants of the vehicles, the general public, or someone else?
