Indeed it would be wonderful, but exactly how viable this technique is remains to be seen. Back when I started using CD burners a typical big hard drive was far smaller than a single CD. (A CD burner was usually hooked up to a dedicated Mac -- always a Mac -- with an unusually large and expensive external hard drive.) If this technology becomes available within, say, five years, it should still be far further ahead of our 4TB SSDs for a good 12 years (assuming Moore's Law in both cases, which is probably optimistic for SSDs). For comparison, CD-Rs probably stopped being useful for backups about fifteen years after I started using them in 1992 (by 2007 it would be a one large or a few small projects on one CD).
