Recently, engineers and scientists gathered at the Global Young Scientists Summit 2017 to discuss moral dilemmas associated with smart technologies, specifically smart cities. They discussed how handing over the reins to autonomous software is always inherently risky, and how their goal was to make the autonomous "invisible" processes as visible as possible. This exemplifies how engineering design requires foresight, responsibility, and value-based decision-making.

a. Provide an example of a new technology that requires engineers to address moral issues when implementing the new technology.

b. Discuss those moral issues.
