One important fact I haven't been mentioning: OAI help tremendously with medium speed takeoffs (fast takeoffs are dangerous for the usual reasons, slow takeoffs mean that we will have moved beyond OAIs by the time the intelligence level hits dangerous), because we can then use them to experiment.

There may be, if the right thing to do is to instead push them to not build an AGI at all.

Interacting with AGI people at the moment (organising a jointish conference), will have a clearer idea of how they react to these ideas at a later stage.
