My wife and I have been keeping a daily journal since our first child was born in 2014 - about 100 - 200 words a day. (And before that i’d been doing it just for myself since 2006.) Besides just having it to go back to and read, something I’m really excited about is llm context windows getting large enough that I can feed the whole thing in (it’s about 1.5 million words) and ask questions. grep only goes so far.
