The model is this: assume that if an AI is created, it's because one researcher, chosen at random from the pool of all researchers, has the key insight; and humanity survives if and only if that researcher is careful and takes safety seriously.

A human alone can't build a superintelligence. So, companies and other organisations are what we should mostly be concerned with. Targetting the engineering talent with the message is probably the wrong approach - you mostly want the managers and directors, since they are more likely to be the ones who willl decide what the machine wants.

I think the low-hanging fruit in getting corporations to behave better is reputation systems - which I discuss here. Merely telling corporations what they are doing is risky seems unlikely to be very effective - corporations are just not that risk-averse.
