Transparency is underrated in the tech industry. But as software systems grow in complexity and their relationship with the real world becomes increasingly fraught, it nevertheless remains a value worth fighting for.But to effectively fight for it, it’s essential to remember that transparency is a technological issue, not just a communication one. Decisions about how software is built and why it’s built in the way that it is lie at the heart of what it means to work in software engineering. Indeed, the industry is in trouble if we can’t see just how important those questions are in relation to everything from system reliability to our collective mental health.
