Depending on the topic in question, one answer could be :
Yes, it is still relevant – albeit diminished in importance – for the following reasons :
- The old has significance, purpose or strengths that the new may not have
- The new creates some problems which can be avoided by simply using what is old.
- Whatever is new is not (yet) accessible to everyone, so the old is still relevant.
However, changes in the world / society compel us to adopt what is new in place of the old OR the new helps us cope with changes in the world / society
