13.4What Stays the Same

Software will always have bugs. Humans will always make mistakes. Systems will always have unexpected interactions. The need for someone who thinks deeply about what can go wrong, who designs defenses against failure, and who advocates for the user when business pressure pushes toward shortcuts — that need will not disappear.

The tools will change. The techniques will evolve. The job title may shift. But the core mission — ensuring that software works correctly, reliably, and in the ways users expect — is permanent.
