Probably not worth it for the same purposes for which binary digital media are currently used (except possibly for long-time archival purposes, if the data density those articles refer to really becomes practical), but thinking in very general "sci-fi"/conceptual way, it could certainly have potential for other purposes, especially when (I assume "when" rather than "if") we eventually develop organic "computing" technology/devices, either in cybernetic form or as standalone "devices" or indeed, life-forms... Again in broad concept, one can certainly at least imagine uses for self-sustaining/self-maintaining "data storage" that doesn't require mechanically or "artificial" chemically-produced power, for example (e.g., an organism that can use ambient heat, light, or kinetic energy to produce electrical energy via biological processes rather than relying on batteries or generators as we currently know them... )
