The correct answer is no.
Explanation:
This question requires a personal answer. In case your opinion is no, you can consider this answer. If your answer is yes, you can model this answer and add your own arguments.
A machine is not like a person. We should not replace people just because they are old, even more if they continue to do their job well. On the contrary, we have someone who has great experience, so it would be useful for that person to continue doing their job.
As for the machines, if they are old and still working in perfect condition, there is no need to change them, unless the new machine contains improvements that the previous one does not.
