A real reduction ins cost means a firm is producing the same output while using less inputs. Those inputs are someone else's output, which necessarily is lower by the amount of cost saved. This loss would be recovered, by the additional spending freed up by the cost savings.
That's not how GDP works. GDP is a measure of final goods and services; intermediate goods and services used to produce those final goods and services aren't counted. When technological advances mean some of those intermediate goods and services are no longer needed and their cost can be saved, that in itself doesn't change GDP at all.
It might be worth rereading the last page or two of posts with that in mind.
