Storing data for thousands of years [video]

I find this project fascinating. I want them to succeed.

I also found other exciting projects in this area:

- 5D optical data storage https://en.wikipedia.org/wiki/5D_optical_data_storage

- DNA Data Storage. To use DNA to store vast amounts of digital data https://en.wikipedia.org/wiki/DNA_digital_data_storage

I have found all these projects inspiring. At the same time, all this seems related to research in the very initial phases.

Here could be an excellent place to share information in this area. I am especially interested in practical, short-term implementations.
