No more BD-R and BD-RE discs huh? I actually have a BD burner, but I have never ever burned a BD, because blank BDs are expensive as f*ck. And these aren't the days of CDs and DVDs, where we didn't have giant-@ss HDD or NASes, or large-capacity flash drives. Back then I and everyone I knew were storing all their sh1t on CDs and then DVDs. But that was a very long time ago. HDD price-per-GB and flash drive sizes + speeds over the last many years have eliminated the need for burning discs, which are also slow. Flash drives are a lot more durable than optical media too. Almost no one I know uses optical media of any kind anymore, especially for personal storage. Everyone has NASes, servers, big-@ss hard drives, and large flash drives.
At least blank CDs and DVDs got super-cheap back in the day. Blank BDs never ever got to the point where they were cost-effective, let alone cheap. I like physical media, but writable/rewritable BDs are all but useless in this day and age.
