Fast forward 25 years, what will audio be like?

Seems like in the past 25 years audio has changed so much - cassettes, cds, servers, hard drives...... composite speaker materials..... network servers..... surround sound - AV systems.....
One can only wonder what systems will consist of 25 years from now.
Clearly there's a trend towards computers meshing with TV/Audio...
I wonder what audiophiles will utilize for components, source material and technologies.
Some aspects of audio become obsolete ex) cassettes yet others like turn tables - LPs, tube based components seem to evolve and endure.
