We are running out of space. Not physical space, but digital space. We are currently living in the "Zettabyte Era." Every day, humanity generates approximately 328.77 million terabytes of data. By 2025, the global "datasphere" is expected to reach 175 zettabytes. From 4K videos, scientific datasets, and autonomous vehicle logs to the massive training models for Generative AI (like BharatGPT), our hunger for data is wildly outpacing our ability to store it. We are generating data faster than we can manufacture the hard drives to hold it. Traditional silicon-based storage (SSDs, HDDs) and magnetic tapes are hitting physical limits in terms of density and durability. They are fragile, temporary, and resource-heavy. Data centers are becoming massive energy drains, competing with entire cities for power grids. But nature solved this problem billions of years ago. Evolution has already perfected the ultimate storage medium: a microscopic, ultra-dense, and energy-neutral ...
