That factory looked like it employed a lot of easily replaceable manual work.
You don't have to replace 100% of workforce, replace just the ones whose work is the easiest to do by a robot.
Replacing 50% of workforce buys you enough time that by the time your available worker pool has shrunk 50%, robotics and AI will be much better and you will be able to replace another big chunk.
Production-wise, shrinking demographics are not such a big deal (they still have a lot of youth unemployment).
Shrinking demographics is a problem due to
a) the ratio of workers vs seniors,
b) shrinking overall demand pool -> shrinking economy
c) smaller overall talent pool -> less diversity, less 'geniuses', i.e. the real drivers of innovation, and less capability to mobilize for great projects
You haven't seem to have accounted for costs. Can the speaker still be produced at the same price? It remains to be seen. A lot of products will simply go away due to economics. Thats a reduced quality of life compared to today.
