It will be interesting to see what happens to physical media in the next decade or so. Nothing is fixed. What we have today for streaming could look very different in terms of content and pricing in future. If these large platforms ever introduce tiered pricing mixed with AI-artist development and promotion, some of their customer base could leave and go seeking physical media or other options.
I just don't see it happening for CDs overall though. One needs a CD player, receiver and speakers to listen to them and younger millennials and gen z don't seem like the demographic that's going to go out of their way to get all of that going. Happy to be wrong on that.
