It is fun and feels new the first time you do it, but that aspect of it is not particularly new to computing. Back then of course, you'd interface with some flat text file database, directories, run commands or use raw sockets to scrape some website to get a result. APIs weren't a thing as much as you'd just try to replicate the queries to submit webpage forms.

You could have a music server in another room and send a message to pick the next song or open the CD drive on some machine halfway around the world. You could write new scripts that operate on a daily schedule and have them running on machines around the world. Many home computers were totally compromised back then too, so almost anything that was connected to IRC was a potential orchestration node.

Having an LLM make decisions about what to do with the machine is a natural evolution of that and not a hard thing to hack on if you have the right model, although it makes totally compromised the new default again.
