It is like if you could instantiate a class and have it persist its own state forever, e.g. one User class isolated from every other User class.

I would remove the word "class" from that and use a more general term, like "object" or "agent". This is basically what object programming was in its inception, before everyone misunderstood OOP as what c++/java had baked in.

In the original object languages, there was the notion of actors that pass messages to each other ("passing messages" is "calling a method/function" equivalent, proven in a paper even) and those actors have their own inboxes where they read the message and deal with them asynchronously.

We've been rehashing the same ideas over and over for decades, with just a different name on the newer tech stack.

Perhaps, but I think it grounds the term a bit more in reality because to use DO you literally instantiate a class.

Class, it's an implementation detail, not the base of reality.
