I once tried to record my terminals 24x7 to save them for memories (and potentially for AI training). I implemented a eBPF based recorder that saves zstd compressed asciicast-v2 format.

But unfortunately it doesn't work on CachyOS's optimized kernel that inlined pty_write() so I stopped doing that.
Here's the MVP project, BTW: https://github.com/kxxt/ttyrecall/

The project is not actively maintained anymore but hopefully might provide some ideas to those that would like to develop alternatives.
