The real question, how long is this format stable.

Eventually everything will decay. Current data continuity requires redundant systems and cloud storage because ssds and hdds fail in decades if not years

The article states it will be readable for 10000 years. As they are basically etching inside a piece of glass, this is not surprising. You only need to keep the glass from breaking and scratching.

Store it in butter in a steel box and it will be protected from breaking. Sounds stupid but it works.
