Most telling is the evolution in our use of prefixes to describe storage needs. From giga- to tera- to peta- to the now routinely contemplated exabytes, technologies will be soon be pushing us into the zettabyte and even yottabyte regimes.1 As illustrated in Figure Figure11,2 the amount of data being generated outpaces our ability to store it, placing tremendous pressure on the storage industry to find improvements in flash, magnetic, and tape memories and to look to new possibilities in fields ranging from molecular structures to nanoscience3 to quantum computing.4 In this issue of ACS Central Science, Mrksich and Whitesides and colleagues describe an elegant embodiment of molecular storage that circumvents many of the synthetic and implementation challenges of the field. %U https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6535776/
