Benja's hope seems reasonable to me.
I'd hope so, since I think I got the idea from you :-)
This is tangential to what this thread is about, but I'd add that I think it's reasonable to have hope that humanity will grow up enough that we can collectively make reasonable decisions about things affecting our then-still-far-distant future. To put it bluntly, if we had an FAI right now I don't think it should be putting a question like "how high is the priority of sending out seed ships to other galaxies ASAP" to a popular vote, but I do think there's reasonable hope that humanity will be able to make that sort of decision for itself eventually. I suppose this is down to definitions, but I tend to visualize FAI as something that is trying to steer the future of humanity; if humanity eventually takes on the responsibility for this itself, then even if for whatever reason it decides to use a powerful optimization process for the special purpose of preventing people from building uFAI, it seems unhelpful to me to gloss this without more qualification as "the friendly AI [... will always ...] stop unsafe AIs from being a big risk", because the latter just sounds to me like we're keeping around the part where it steers the fate of humanity as well.
One open question in AI risk strategy is: Can we trust the world's elite decision-makers (hereafter "elites") to navigate the creation of human-level AI (and beyond) just fine, without the kinds of special efforts that e.g. Bostrom and Yudkowsky think are needed?
Some reasons for concern include:
But if you were trying to argue for hope, you might argue along these lines (presented for the sake of argument; I don't actually endorse this argument):
The basic structure of this 'argument for hope' is due to Carl Shulman, though he doesn't necessarily endorse the details. (Also, it's just a rough argument, and as stated is not deductively valid.)
Personally, I am not very comforted by this argument because:
Obviously, there's a lot more for me to spell out here, and some of it may be unclear. The reason I'm posting these thoughts in such a rough state is so that MIRI can get some help on our research into this question.
In particular, I'd like to know:
