This type of thinking also follows from decades of experience.
For some reason the software engineering world largely abandoned esteem and respect for all of the above.
To imply this was a software bug is a pretty silly representation - the system was poorly engineered and didn't have proper contingencies for sensor disagreement. This is pretty clearly a design/engineering error with a software component.
Besides, the guy said "rarely ever matter" for a reason, not "explicitly never impact things"... Bit of a silly comment from you IMO
