> Knowledge should be communal and free

I agree, which is why I license my work under copyleft licenses such as AGPLv3 so that anyone has to make their modifications public too.

I think LLMs (especially closed-source models) will make this worse.

Free and communal knowledge means you're easily replaceble by someone else.

I wonder what communal answer you have for someone who would say, "moi2388, your work will be now done by moi2389. Thanks and good bye."
