However I must say that there is a small factual correction to be made to the article. Glass doesn't last forever. Glass is a liquid, albeit a very viscous one. Anyone who has seen the curvature on old windows knows what I mean – Glass sags with time, and this will cause deformations to the stored data patterns, causing the storage mechanism to fail. But it certainly will be able to store data for longer than my lifespan.

This Small Piece of Glass Stores Data Forever
When you order food to your apartment from your phone while on public transit on the way to said apartment, it’s readily apparent that we’re living in some kind of sci-fi future. We may not have flyin…

The sag in old windows is not due to deformation over time, but due to the method of making glass flat that was in use at the time. It is possible to find old buildings where the panes were installed in other orientations, and the 'fatter' part is at the top, or one of the sides, rather than the bottom. Installing the wider portion at the bottom is more structurally sound, which is why it is the more common pattern.

They have some very cogent examples, such as the presence of glass artifacts in Egyptian tombs which at the rate of flow needed to explain the 'thickened base' of windows would be a puddle, or spyglasses and telescopes from the 1600's and before that are still optically usable, whereas if the glass had flowed, their optical properties would have been quickly rendered useless.
Glass is not a liquid. That's an old misconception.
+Sophie Wrobel we can mix in other molecules to help maintain the structure of the "glass". We can definitely make them last a lifetime now at least.
