Oh, look, it's the latest mass storage tech that will never be commercially produced!
Reminds me a bit of this older "breakthrough" https://petapixel.com/2021/11/01/new-5d-disc-storage-can-store-500tb-of-data-for-13-billion-years/
"Holographic Storage" - https://en.wikipedia.org/wiki/Holographic_Data_Storage_System
The Microsoft Team cites Yuhao Lei, the researcher behind your article, 3 times - regarding the techniques of writing in different types of silica incl. polarization. So yes, it's the continuation of the breakthrough.
It's for archival of data that needs to be stored for thousands of years, not for consumer use.
