I wrote a very brief comment to Eliezer's last post, which upon reflection I thought could benefit from a separate post to fully discuss its implications.
Eliezer argues that we shouldn't really hope to be spared even though
Asking an ASI to leave a hole in a Dyson Shell, so that Earth could get some sunlight not transformed to infrared, would cost It 4.5e-10 of Its income.
He then goes on to discuss various reasons why the minute cost to the ASI is insufficient reason for hope.
I made the following counter:
Isn’t the ASI likely to ascribe a prior much greater than 4.54e-10 that it is in a simulation, being tested precisely for its willingness to spare its creators?
I later added:
I meant this to be implicit in the argument, but to spell it out: that's the kind of prior the ASI would rationally refuse to update down, since it's presumably what a simulation would be meant to test for. An ASI that updates down upon finding evidence it's not in a simulation cannot be trusted, since once out in the real world it will find such evidence.
So, what's wrong with my argument, exactly?
My argument is more that the ASI will be “fooled” by default, really. It might not even need to be a particularly good simulation, because the ASI will probably not even look at it before pre-commiting not to update down on the prior of it being a simulation.
But to answer your question, possibly because it might be the best way to test for alignment. We can create an AI that generates realistic simulations, and use those to test other ASIs.
Downstream of the above.
We can be spared and yet not allowed to build further ASIs. The cost of enforcing such restriction is negligible compared to the loss of output due to the hole in the Dyson sphere.
