Invisible line

noun phrase

The gap between what AI can theoretically do and what people are willing or able to trust it to do in real work.

Also known as capability–trust gap

The invisible line is the distance between what AI can do in theory and what people actually hand over to it at work. Part of the gap is technical: the tool may not be good enough, the systems may not connect, the data may not be allowed to leave the building. The rest is human: context nobody wrote down, consequences somebody must own, and the checking that eats the hour the machine supposedly saved. The line moves as tools improve. It does not vanish because a benchmark rises. Work crosses it when somebody judges the benefit worth the risk and puts their name near the result. The valuable skill is knowing what can safely be handed over, and which part would be dangerous to lose.
