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 or 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 consumes the hour the machine supposedly saved.
The line moves as the tools improve. It does not vanish simply because a benchmark rises. Work crosses it when somebody judges that the benefit is worth the risk and puts their name near the result. The valuable skill is not refusing to delegate. It is knowing what can be given away and which part would be dangerous to lose.
