automated: is an environment when your wife tels you: “this is your purchase order”
autonomous: is same, but just wit small difference - the purchase order is initiator, but you will purchase something by your own decision (learned from man practice)
When first is easy to all of us. We’ve got an order, and know what to do.
Second is dangerous, because you will heading to trubles - to explain “why did you purchase these stuffs/ or not purchase from the order?”
