The main types of technology ethical dilemmas and crisis involve efficiency and equality, benefit and risk, risk and privilege, science and belief, and status of science and technology in society. The main types of technology ethical dilemmas and crisis involve efficiency and equality, benefit and risk, risk and privilege, science and belief, and status of science and technology in society.
