20.10 CONCLUSION

Technical standards ensure AI systems built on solid foundation. Excellence in engineering prevents failures. Discipline enables innovation.

Standards are not bureaucracy. Standards are professionalism.

When code is clean, when systems are resilient, when documentation is clear—safety becomes achievable.

Build it right. Build it safe. Build it well.
