WAHa says yes.
Dr. Hannu Kari, grand god of the norse viking ip network says no.
I'm personally undecided, because you cannot phase out "physical" media before everyone of the current main market share generation has died. Looking at average lifespans, that might just last long enough to let another type of media rise to popularity.
On the other hand, people might be reluctant to give up on cds for the next 1'000 years (I hear vinyl is rather strong still in some areas) because of the slew of new machinery that would need to be bought, and people would whine so much about perceived "quality loss" in the new media format that it could never gain a real foothold.
