I guess I will break my recently self-imposed rule of not talking about this anymore.
I can certainly envision a future where multiple powerful AGIs fight against each other and are used as weapons, some might be rogue AGIs and some others might be at the service of human-controlled institutions (such as Nation Estates). To put it more clearly: I have trouble imagining a future where something along these lines DOES NOT end up happening.
But, this is NOT what Eliezer is saying. Eliezer is saying:
The Alignment problem has to be solved AT THE FIRST TRY because once you create this AGI we are dead in a matter of days (maybe weeks/months, it does not matter). If someone thinks that Eliezer is saying something else, I think they are not listening properly. Eliezer can have many flaws but lack of clarity is not one of them.
In general, I think this is a textbook example of the Motte and Baley fallacy. The Motte is: AGI can be dangerous, AGI will kill people, AGI will be very powerful. The Baley is: AGI creation means the imminent destruction of all human life and therefore we need to stop now all developments.
I never discussed the Motte. I do agree with that.
I would certainly appreciate knowing the reason for the downvotes
