"Fascinating! You should definitely look into this. Fortunately, my own research has no chance of producing a super intelligent AGI, so I'll continue. Good luck son! The government should give you more money."
Stuart Armstrong paraphrasing a typical AI researcher
I forgot to mention in my last post why "AI risk" might be a bad phrase even to denote the problem of UFAI. It brings to mind analogies like physics catastrophes or astronomical disasters, and lets AI researchers think that their work is ok as long as they have little chance of immediately destroying Earth. But the real problem we face is how to build or become a superintelligence that shares our values, and given that this seems very difficult, any progress that doesn't contribute to the solution but brings forward the date by which we must solve it (or be stuck with something very suboptimal even if it doesn't kill us), is bad. The word "risk" connotes a small chance of something bad suddenly happening, but slow steady progress towards losing the future is just as worrisome.
The usual way of stating the problem also invites lots of debate that are largely beside the point (as far as determining how serious the problem is), like whether intelligence explosion is possible, or whether a superintelligence can have arbitrary goals, or how sure we are that a non-Friendly superintelligence will destroy human civilization. If someone wants to question the importance of facing this problem, they really instead need to argue that a superintelligence isn't possible (not even a modest one), or that the future will turn out to be close to the best possible just by everyone pushing forward their own research without any concern for the big picture, or perhaps that we really don't care very much about the far future and distant strangers and should pursue AI progress just for the immediate benefits.
(This is an expanded version of a previous comment.)
Think of the tool and its human user as a single system. As long as the system is limited by the human's intelligence then it will not be as powerful as a system consisting of the same tool driven by a superhuman intelligence. And if the system isn't limited by the human's intelligence then the tool is making decisions, it is an AI, and we're facing the problem of making it follow the operator's will. (And didn't you mean to say "as powerful as any (U)FAI"?)
In general, it doesn't make much sense to draw a sharp distinction between tools and wills that use them. How do you draw the line in the case of a self-modifying AI?
Reasoning by cooked anecdote? Why speak of tanks and not, for example, automated biochemistry labs? I can imagine such existing in the future. And one of those could win the war against all the other biochemistry labs in the world and the rest of the biosphere too, if it were driven by a superior intelligence.
