[SystemSafety] New paper on MISRA C

[Paul Sherwood]

Hi folks,
I'm new here, but somewhat confused.

The group is "SystemSafety", which I take to mean that this community 
understands that safety is a property of a system, not component level.

As I understand it MIT and others have successfully debunked the notion 
that system safety is correlated with component reliability.

So a simple question, and sorry for being blunt...

Why is MISRA C still considered relevant to system safety in 2018?
