Why do people want logs of conversations for years and years?

All of my Signal chats are set to 4 week expiry. Any media I want to keep, I save to the device.

I don’t audio record my conversations with close friends and family; why would I keep chat logs?

I don’t understand why people demand this feature. It wasn’t until the iPhone that people got accustomed to keeping every text for all time.

I don’t think it’s a healthy approach. For most of human history, you didn’t get a permanent record of private conversations you had with people. It feels like a type of hoarding, given how often people actually use/access their old (>4 weeks) chat logs.
