To my knowledge, there have been very few aircraft incidents caused by software.

Unless you consider the lack of it; both in aircraft and on the ground in development processes. Just one example here to drive the thought: wind shear.

Actually, they now have systems designed to detect wind shear.

But, one cannot consider the lack of a system (including software) to perform a function as having the software contribute to a failure caused by the lack of that system.

That’s kind of like saying “I turned into the wrong driveway and hit a tree I didn’t have”.
