Lol. But seriously, the irony is CD-ROM's degrade to completely unusable within a century due to disc rot. A CD-ROM made with gold and completely encapsulated in an extremely stable enamel might work. Then, leaving universal instructions as to how to use said CD-ROM is important, rather than arrogantly presumptive anthropocentrism.
Do you think NASA burned a 24x CD-ROM from their PC and added it to New Horizons?
A CD-ROM rots fast due to the deyes, but what about a normal pressed CD of aluminum? Those should be pretty stable. I have only seen those destroyed with sunlight.
