CDs yes, but point of fact wikipedia says DVDs are actually (very slightly) younger than USB. Regardless, surely that's just more examples in favor of us being able to still read widely-deployed tech in 50 years? I'll grant that with the right materials, under the right conditions, optical media might well outlive this thing, but that 1. contains important caveats (plenty of optical media degrades within <5 years AIUI) and 2. doesn't invalidate the usefulness of this, just offers other options.
