Just a thought, but it might also be the training.   My Dad (a
mathematician and 'computer') passed a few years ago, I'd love to have
asked him.   But I suspect when he and his peeps were doing this with a
slide rule or at best an Friden mechanical adding machine, they were
acutely aware of how errors accumulated or not.  When they started to
convert their processes/techniques to Fortran in the early 1960s, I agree
with you that I think they were conscious of what they were doing.   I'm
not sure modern CS types are taught the same things as what might be taught
in a course being run by a pure scientist who cares in the same way folks
like our mothers and fathers did in the 1950s and 60s.
