> I don't comprehend how you made no mistakes on the journey after drafting the PCBs and writing drivers. From my POV as a software developer, C has so many pitfalls that it is incomprehensible to me that things will Just Work, especially in the context of something that is meant to run for a very long time and not be "restarted."

Process, design and architecture play a larger role in the bugcount than language choice.

I wrote munitions control software in C; many of the systems that would cause loss of human life were written in C for decades.

The recent meme of "if it's written in C it must mean unreliable" is inaccurate - all the most reliable systems, for decades, were written in C.
