Tape storage 100% is still a thing and is valued for a lot of truly critical data.
Also, WAY too much critical infrastructure still depends on floppy drives because... there is not a good reason to upgrade the hardware when they need data on the order of hundreds of kilobytes every couple of months.
Storage with purpose will be preserved. Maybe not in a computer sold in best buy but very much in "computing" as a whole.
I can't think of any situation where THIS disc is useful. But optical drives themselves are 100% going to remain a thing because they provide write once data storage (and OS installation) which is incredibly useful in secure environments.
