I don't know... I mean Nick Cave and the Bad Seeds did the Murder Ballads as kind of a lark and yet some of the songs are absolutely wonderful and based on trad songs.

Bruce Springsteen produced an album of American folk not too long ago.    Johnny Depp and a load of Hollywood types released an good album of sea shanties.

I see generations in future happening onto these recordings and digging deeper for sources as they have been doing for yonks. Classical composers did it, Blues musicians did and still do it, Rock, Country, New Age, etc.

Someone will always go back to recordings of source singers. Some will render those songs just as they learned from the source recordings, some will modify them.

I have been looking at tune sessions on youtube and they are packed with young people. I look up blues guitar, mandolin, whistle and lap dulcimer tutorials some of which are taught by young musicians.

I think it's wonderful. I don't see the demise of trad music at all.
