> Do you really think physical disc and media players for them will last long?

Yes.

There are too many use cases for physical and immutable long-term offline storage for this niche to go unfilled, but the niche is too small (at present) to prompt the development of a replacement medium and format, so while I am sure that the materials and read/write hardware will continue to evolve (better data longevity guarantees, read/write speed, physical durability, etc.) the implementations will remain compatible, or at least the reading ones will.
