Please do not give me shit for using Facebook. It’s how I keep in touch with relatives, most of whom live abroad, and my brother, who is has ASD prefers to communicate with me that way.
I would rather not use it, but I would prefer keeping in touch with my brother.
That said, I would not let AI keep in touch with my brother for me.
The fediverse is alive and active, but unfortunately every single account is just an alt of The Picard Manouver.
