My personal conspiracy theory is that Sony is trying to kill Blu-ray before it enters public domain. (2028-2030 or so). Single-layer Blu-rays are invaluable for my cold storage backups. So I'm going to keep buying them. And thanks to them, entering public domain, innovation will be possible once again. So, in all honesty, I don't have that much to fear, as mega corporations also use blu-rays heavily for backups, together with tape.

    How's the long-term stability of Blu-Ray? I know we're running into problems with magnetic tape and CDs degrading.

    Magnetic tape depolarizes over time. CDs were organic and they would literally rot away. But as long as your Blu-ray discs are high to low (HTL)/inorganic Then you're really set for at least 30 years as well, just like professional tape, but at a fraction of the price.

    There's M-Discs which are supposed to last 100 years I've heard.

    I have 30+ year old CDs still readable.

    I also have CDs that are this old. There's a big difference between CDs that you can burn yourself, because those are using organic materials and the weak laser in your disk drive to burn them and professionally made disks, which are usually using inorganic materials and molds. The molds then are embossed into the datalayer of the CD, making it significantly more durable than organic discs.
