Simple embedded systems questions. New SW engineer as a manager for a new FW group and spent 15 minutes debating why FW and SW are different. The manager said they are the same and I disagree as any rea FW guy knows. This was a waste of time and quickly showed the persona of the manager. He then asked if a remote control (IR) is a FW or SW if it had a display since I generalized that FW works and I/F with HW and SW is more for user interface. Really?
