You seem to be as ignorant about the practices of
software as you are about the practise of Morse Code

RTOS's have been in regular use in Britland industry
for well over 35 years.

If the "demand for much of the core software" was reduced in the
systems for which you were responsible, why did they go on for
so long, and why did you ultimately have to leave and get a job
as a teacher?

The move to the use of
real time operating systems has also reduced the demand for much of the
core
software.
