Absolutely! Thank you!

The software must be designed within the bounds of failure mode analysis
and the best behavior of the software is going to be entirely dependent
on the application at hand. Exception raising, etc. is going to do
*nothing good* for you unless you first look at how the system might
fail and what the consequences will be in the face of that failure. You
have to spend an enormous amount of time throwing out scenarios of
possible failure and asking what sort of accommodations you might make
to mitigate the failure.

I was once seriously asked: "Suppose that the CPU fails, what can you do
in software to detect this and accommodate it?"
