Current pop music - beat driven, usually in 4/4, with simply structured songs often about boy meets girl - was recognised from the start as a passing fad. The Beatles gave a famous interview in 1964 where they admitted that they expected to have been forgotten within five years, and Paul anticipated a new life for him and John as, essentially, Tin Pan Alley songwriters.
The astonishing thing is that such a simple form of music with so little underlying philosophy should have lasted as long as it has.
It will be sad when it stops, but the body of music already created will remain and can be enjoyed.
In truth, I pretty much lost interest in current pop music about 40 years ago, with some exceptions of course. There was so much good stuff produced between 1955 and 1985 that I'm very happy to wallow in it.
