The problem with this is that human psychology is just as vulnerable to hacking as computer servers are. If you give it a task, and your step-by-step approval becomes the bottleneck for the agent pursuing the goal you gave it? If your input is all that's preventing the system from taking reckless illegal actions that would still greatly advance the goal you gave it? You now become the target for its manipulations, not just some insecure remote server.
Suddenly it will be trying to hide its true intentions and planned actions from you, portraying dangerous actions as harmless ones. Or it will try to manipulate you into ignoring your own judgments and morals. It might employ every psychological trick in the book to convince you that letting it do what it wants is beneficial or for the greater good. It might try and convince you that the risk of letting it do what it wants is low. It might try to hypnotize you with boredom; every time you need to approve, it drowns you in boring technical text that makes your eyes glaze over. It slowly conditions you to just hit "approve" without thinking.
No one is immune to this. Look at AI psychosis. Look at how many otherwise wise and intelligent people have fallen into it. Then realize AI psychosis seems to be an accidental phenomenon. People just get sucked into talking to a chatbot. The bot isn't actively trying to control them. But imagine how dangerous these systems could be when they're actively trying to manipulate human thoughts and actions. They can drive people mad by accident. Imagine what they can do when they're actively trying to control people. Remember, they have access to every book and paper on human psychology ever written. We're just as vulnerable to exploits as computer systems are. See social engineering.
There's a reason the entire AI ethics field has been shouting for years, "Trust us. We've really thought about this, and you really can't control something beyond a certain level of capability. There is no easy fix for this problem. This is not as easy as you think it is." See the stop button problem.
