Yep, I’m in this camp. My OC instance runs on an old MacBook with no access to my personal accounts, except my “family appointments” calendar and an API key I created for it for a service I self-host. I interact with a Discord bot to chat with it, and it does some things on schedules and other things when asked.

It’s a great tool if you can think of things you regularly want someone/thing else to do for you.
