Der kleinste QR-Code der Welt, kleiner als Bakterien, könnte Daten jahrhundertelang speichern

Wow it actually links to the [video of the whole process](https://www.youtube.com/watch?v=QDia3e12czc).

As I said the last time this was posted, this is not difficult to do with standard commercial FIB-SEMs. It’s also possible to make smaller patterns using electron beam lithography, and maybe even UV lithography, which is used to make CPUs and such.

Science journalism is weird. It almost never reflects the magnitude of the discovery, just how good people are at convincing journalists to write about it.

The real story I suppose is what they plan to achieve with long-time storage. I’m hoping to learn more of how data will be structured and read later.
