The claim that we're reaching the limits of storage technology (SSDs, spinning rust and tape) is false. The amount of storage produced each year is determined by demand, and there isn't a demand signal asking for 10X or more. Even if DNA storage is created, it will be more expensive and less reliable than existing tech for decades- likely more, due to the innovator's dilemma. If you want to store lots of data for a long time (like deep time) use lithography on quartz.
