I think all of us on this list appreciate the need for the risk assessment
to be performed. However, there is a class of system out there where
such risk assessment has not been performed and because the
developers had not performed the risk assessment, they unkowingly
release a system into the wild that somehow causes harm.

How many normal courses in engineering routinely direct the participants
to the idea that a risk assessment should be performed regardless of
whether or not someone thinks the system may become safety related
or is benign.

There is a big wide world of people out there that have no clue of this and
we need to have a mechanism by which we educate the rest. Knowing that
we will likely fail in that regard for any but a small proportion. To this dilema,
I have no answer except that I try through my efforts in schools as a STEM
Ambassador, to introduce the concept of risk assessment for the young.
