I ripped my CDs 20 years ago and kept that library, moving it between machines and backing up to the cloud. I don't see why I can't keep it alive for another 20 or 30 years. Over time this has become much easier as storage has become smaller and cheaper. I now have my entire music collection on a microSD card on my phone which as well as being handy is also another backup.

Only real problem is that I ripped them at 128Kbps. For some tracks I've gone back and re-done them at a higher bitrate.
