Have you heard about the “Therac-25 incident”?
The Therac-25 was a radiation therapy machine used for cancer treatment in the 1980s.

Safety-Critical Design Practices: The importance of applying safety-critical design practices, such as redundant systems, fail-safes, and thorough risk analysis, especially in systems that can cause information leakage or harm if they malfunction.
