I worked with Greg Brockman in the mid-2010s. Once, as we were walking down Folsom street, I explained Eliezer Yudkowsky's "AI Box" experiment to him[1]. He said something to the effect of "that's ridiculous - I would simply not let it out of the box." We agreed to try it out some day, but never did. [1]: http://sl4.org/archive/0203/3132.html
We can only hope to either never create an AI so strong or to align it correctly. But if it is not aligned and only “contained” then it won't ever be safe.
