Depends I guess. I still have a ZX81, Atary TT, STfm, STe and Falcon. The original PC will probably be spared, as will Commodore C64, 128, Amiga,… Current PC hardware probably not.
Old cars can still be repaired and used for their original function. Also, their looks are still pleasing to some. Cars from before they added computers to them are also a lot easier to repair and for those enthousiasts a hobby to have fun with.
With electronics (all, not just computers) it’s usually replaced when broken instead of repaired, so I guess most will be lost.
A CD/DVD is a read only digital information carrier. It holds files which you copy when you rip the DD/DVD. The data is stored as indents in the surface marking untuched surface as 0 and indents as 1 (or the other way around).
The only way to damage CD/DVD data is physical, scratching the surface (changing the path of the laser light needed to read the data) or breaking the disc (making it unusable in the drive).
