THE PURPOSE OF CONTINUOUS INTEGRATION IS TO FAIL

Summary from the TLDR Dev newsletter

Continuous Integration (CI) provides value not when it passes, but specifically when it fails, as its primary purpose is to catch mistakes early in the development process. Without CI, errors are only detected after deployment, resulting in long, manual, and dangerous feedback loops where problems can cause significant damage. A failing CI run acts as a safety net, preventing erroneous code from reaching users and offering a much shorter, automated, and safer feedback mechanism.
