Ethical Principles and Vigilance in Software Development

Key Insight

The immense and unexpected power held by developers demands constant vigilance, as their software now weaves the very fabric of daily modern life, directly affecting people. Developers have a duty to ask two critical questions about every piece of code they deliver: 'Have I protected the user?' and 'Would I use this myself?'.

Protecting users requires proactive measures such as implementing ongoing security patches for devices like baby monitors, ensuring manual control if an automatic central heating thermostat fails, and storing only necessary data while encrypting personal information. While acknowledging human imperfection, developers bear responsibility if they do not conscientiously attempt to list all consequences and protect users from them, aligning with the principle: 'First, Do No Harm'.

The 'Golden Rule' applied to software development means being happy to be a user of one's own software. This involves considering whether one's details or movements should be shared with retail outlets, or if one would feel safe in an autonomous vehicle built by them. If inventive ideas skirt ethical boundaries, developers are equally responsible as project sponsors, regardless of rationalized degrees of separation, and must adhere to the rule: 'Don't Enable Scumbags'. Developers are called to envision and courageously build a desirable future, having the courage to say 'no!' to actions that go against this ideal.
