As for the technical nature of this, I'm not sure if I've totally understood correctly despite how well it's written, but are they essentially holding back sort of unweighted parameters built in to the model architecture which they can then populate with new context during 'sleep' and then using the techniques outlined in the 'dream' section to reinforce what gets stored in those MoE weights? That to me seems like a solution which only Google is best placed to solve due to their fully integrated AI stack and historic experience with hardware optimisation, but which would be rather hard to do if you are a more resource and compute constrained organisation
