Ask HN: I think the AI terminology needs a reset

A friend asked me what a personal AI agent does. I started explaining, then I realized I was describing three different things.

I think we need better order and terms in this world.

So personal ai agent can be 3 different things..

Delegate agent: It's own inbox, number, and accounts. Like: "Hi, i'm Peter the agent of Ana, I'd like a table for four"

Twin agent: My accounts, but it says an agent is speaking. Like: "Hi, I'm Ana, through her agent, I'd like a table for four"

Ghost agent: My accounts, without mentioning AI. Like: "Hi, I'm Ana, I'd like a table for four"

Also the term "personal ai agent", I'm not sure if its the right term, like i think what makes this agent special that its "always on" right? not that its personal.. theoretically it can work for entire team..

I would like to know what you think and if you have better ideas
