While technically this is rooted in the technological misconstruction of a missing separation of data and instructions.

However my point is: on the other hand, that would be the same if you outsourced those tasks to a human, isn't it? I mean sure, a human can be liable and have morals and (ideally) common sense, but most major screw ups can't be fixed by paying a fine and penalty only.

Yes and no. You're right to notice that this is an example of a more general problem called the principal-agent problem. https://en.wikipedia.org/wiki/Principal%E2%80%93agent_proble...

We have no general-purpose solutions to the principal-agent problem, but we have partial solutions, and they only work on humans: make the human liable for misconduct, pay the human a percentage of the profits for doing a good job, build a culture where dishonesty is shameful.

The "lethal trifecta" is just like that other infamously unsolvable problem, but harder. (If you could solve the lethal trifecta, you could solve the principal-agent problem, too.)

Since we've been dealing with the principal-agent problem in various forms for all of human history, I don't feel lucky that we'll solve a more difficult version of it in our lifetime. I think we'll probably never solve it.

A person can be blamed though. And people have a social fabric with understanding about human mistakes or even about people having lied to your etc.

We have no such thing for AI yet.
