There's a significant difference between a human "in" the loop and "on" the loop.
In the loop means that a human is required for the loop to move forward.
On the loop means the human is able to correct the loop but it can move forward autonomously.
A massive difference in efficiency.
If you are in the loop you are the bottleneck.
You have to let go of the loop, so it can go arbitrarily fast.
When you let go of the loop your system can fly.
If you want to maximize the AI system's impact for you, you have to not be a limiting factor.
