I hope such a document addresses the Mañana response: yeah, sure, figuring out how to control the AIs and make sure they're friendly is important, but there's no time pressure. It's not like powerful AI is going to be here anytime soon. In fact it's probably impossible to figure out how to control the AI, since we still have no idea how it will work.

I expect this kind of response is common among AI researchers, who do believe in the possibility of AI, but, having an up-close view of the sorry state of the field, have trouble getting excited about prophecies of doom.
