What if friendliness is not a property of the technology, but of the use? With all the potential concerns of AGI, I think nuclear technology is a good analogue. It has great potential for peaceful use, but proliferation of nuclear weapons is a so-far inseparable problem of the technology. It's also relatively easy to use nuclear technology unsafely compared to safely.

The precedent for general intelligence is not good. The only example we know of (ourselves) is a known existential threat.
