How many will listen to tape and vinyl in the next century?


Something between 500 and 1000 people, maybe?

I make/grind my own coffee, I use a double edge razor/shaving brush, I listen to vinyl....  these are processes toward perfection. ( can you tell I'm an old guy)
How many? Take the highest percentage pure copper in speaker cables, consider the remainder percentage, apply a coefficient far less than 1, multiply the result by the worlds population at 2100AD and obtain an overestimate proportional to the coefficient.

Possibly my grandson, he is now 1 and 1/2. Maybe other grandchildren who's grandfathers have a vinyl system that they hear at early age.

Interesting, I believe there are turntables that could be maintained for that length of time, vinyl disks also.
