Can't be that much of a mystery? Less weight, less space, less cost, less clunky mechanical stuff - given almost nobody would ever use them it's a no-brainer.
Don't you think that's sort of a self-fulfilling prophecy? DVDs are absolutely not obsolete, and are still manufactured. Lots of content exists on DVD but not streaming. We get movies and shows at the library all the time that are not on any streaming platform.
Sure, everybody has a computer built only to stream, so streaming is the default for anybody who doesn't want to carry an external drive in their laptop bag. Design decisions influence how your product is used. Surprise, people who have phones without headphones jacks are less likely to use wired headphones.
And you can send audio over USB. You can't possibly have more than 10 Gbps of audio?
