Personal wiki's impersonally compiled. I gauge LLMs for the extent they fray the social fabric that hold people and society together. And the way AI is introduced for max disruption causes me to be generally against the technology, despite that there are also obvious merits. Here it depends on how much value, say, a family gets out of reading in their family encyclopedia.

It is a nice idea, and I can imagine how it may serve to strengthen the family's social cohesion, in a time where everyone is busy doing the rat race. Though I'd not use it as "encyclopedia", a cold-hearted fact recorder, more like more a social-focused "Our Family Diaries" and would be much better served by family members writing down their own experiences.
