Dan Hendrycks, Eric Schmidt and Alexandr Wang released an extensive paper titled Superintelligence Strategy. There is also an op-ed in Time that summarizes.

The major AI labs expect superintelligence to arrive soon. They might be wrong about that, but at minimum we need to take the possibility seriously.

At a minimum, the possibility of imminent superintelligence will be highly destabilizing. Even if you do not believe it represents an existential risk to humanity (and if so you are very wrong about that) the imminent development of superintelligence is an existential threat to the power of everyone not developing it.

Planning a realistic approach to that scenario is necessary.

What would it look like to take superintelligence seriously? What would it look like if everyone took superintelligence seriously, before it was developed?
