This document summarizes a lightning talk on ethics given at Techfestival in Copenhagen, Denmark. It discusses the history of computing and how individual ownership has grown dramatically. It then explores the definitions of morals and ethics and how companies must consider ethical issues like privacy, security, intellectual property, diversity and inclusion when developing technologies. The talk encourages signing an open letter called the Copenhagen Letter that commits to these ethical values and asks important questions about responsibility and fairness. It provides the website for the letter and invites the audience to join in the discussion.
