Fast forward 25 years, what will audio be like?

If there is no money in it seldom comes to pass.
Very seldom.

Music will remain timeless no matter which genre one prefers. If it takes you to "that place".

Better sound more readily available, more music than ever to listen to. :-)

Same thing 50, 100, 200 years, in the year 2525..."if man is still alive". :-(

Very true Joman, but both heaven and hell are "places".

I wish I could share your optimism about the near future. The trajectory I see has us fully indentured and thoroughly under control of the plutocrats who are taking control of everything from the Supreme Court to the food sources. DNA and GPS will prove to be formidable control and punishment tools. We will be competing desperately for any opportunity to earn any amount of money and we will have nowhere to house a system even if we could buy one.

Picture the West Virginia coal mining town represented in literature and song. The stores and the housing all belong to the company who will evict you for the slightest provocation. All of the rights you had bestowed by the vestiges of organized labor have been lost. No limits on days or hours worked. No vacations, sick days or holidays. No raises. You work until you no longer can and are then discarded. Since the company controls both your wages and your cost of living, they can calibrate both to keep you in debt for life.

Under circumstances like that, audio will be an impossible luxury. You'll be making your own instruments from discarded objects and whatever you can scrounge from the remnants of Mother Nature. The good news is you will be able to sing the blues like never before. 2039
