I think the key thing they were pointing out was the ability to store information inside a nucleus that can be read back (reminds me of how core memory worked on the old Apollo 11 Era computers) which could be a very reliable and dense memory. It's reliable because the electron shell is sort of protecting the information stored inside the nucleus.

I wonder if they'll have the same issue that core memory also had which is that by reading the magnetic state you also destroy that state, and so every bit 'read' operation has to be followed with a 'now write the bit back again' step.
