You need to treat her better 🥺

Probably not in the way you're thinking, just because memory isn't encoded like that. Just like our normal cognitive processes, memory uses a bunch of heuristics (or shortcuts) to get the most bang for your buck, synaptic efficiency wise. Because of this, it would likely be impossible to recreate a memory fully based on existing data after the fact because that much data just isn't collected and stored (as far as we know).

The best way for a technology like this to exist with our current understanding (which changes daily!) would be for everyone to wear a camera all the time and backup their recordings each day. Lol.
