The end of physical media is neigh

Yes. A paid download can be stored on your HD and copied, moved, and backed up however you wish. You own the file.

@cleeds  Thanks.  That’s what I would’ve thought but wasn’t sure.  It makes total sense. 

There are a ton of 8 track players for sale on ebay, so CD and blu-ray players should be available for as long as you'll be around.  You probably have more CDs, etc. than you could listen to in your remaining lifetime, why worry?

Hogwash. There are and will almost certainly be used cds and stores to sell them. Every time I go to the music store I see plenty of people buying physical media of all sorts. Mostly LPs but cds too. My Oppo UDP-205 player still works great (just used it tonight) and I imagine it will for a lot longer. 

In around 2002 I started streaming. I also burnt the songs I purchased on CDs. Eventually the CDs stopped playing. I went back to CDs and vinyl and never looked back/ never missed streaming. (Unless we call watching youtube streaming)

Try to buy a composer of the Franco-Flemish school as Obrecht on vinyl ?

I dont want vinyl... It is useless for world music (india-Persia Africa)

I dont want cd.......

The same problem exist for books...

The books i want you will not discover them in most University...

Their cost will be very high in many case...

When i bought the handbook of logic 40 years ago i paid it 80 dollars... Imagine the cost with the inflation calculator...

the 25 books of the linguist that interest me cost 40 dollars each book ...

Do you think i will go with my life without these essential books ?

No ...

Then it is like audio : the solution is studying acoustic...

For the books it is knowing internet...

Life is too short to live without the tools necessary to think ...

i never had the budget to create my audio system  as i dreamed of...

I discover that a very good hi-fi cost peanuts if we learn how to do it...

We must study not buy...
