Finally, some quantification!
Here's a sequence of interpretations of this passage, in decreasing order of strength:
I would be very grateful to see the weakest of these claims, number 4, supported with some calculations.
Of course I wish that there was a date attached to these claims. Easily greater than 10% chance that we'll be wiped out in the next 50 years?
Well, let's start with the conditional probability if humans don't find some other way to kill ourselves or end civilization before it comes to this. Eliezer seems to argue the following:
A. Given we survive long enough, we'll find a way to write a self-modifying program that has, or can develop, human-level intelligence. (The capacity for self-modification follows from 'artificial human intelligence,' but since we've just seen links to writers ignoring that fact I thought I'd state it explicitly.) This necessarily gives the AI the potential for greater-tha...

His answer, as far as I can tell, seems to be that his Azimuth Project does trump the possibility of working directly on friendly AI or to support it indirectly by making and contributing money.
It seems that he and other people who understand all the arguments in favor of friendly AI and yet decide to ignore it, or disregard it as unfeasible, are rationalizing.
I myself took a different route, I was rather trying to prove to myself that the whole idea of AI going FOOM is somehow flawed rather than trying to come up with justifications for why it would be better to work on something else.
I still have some doubts though. Is it really enough to observe that the arguments in favor of AI going FOOM are logically valid? When should one disregard tiny probabilities of vast utilities and wait for empirical evidence? Yet I think that compared to the alternatives the arguments in favor of friendly AI are water-tight.
The problem why I and other people seem to be reluctant to accept that it is rational to support friendly AI research is that the consequences are unbearable. Robin Hanson recently described the problem:
I believe that people like me feel that to fully accept the importance of friendly AI research would deprive us of the things we value and need.
I feel that I wouldn't be able to justify what I value on the grounds of needing such things. It feels like that I could and should overcome everything that isn't either directly contributing to FAI research or that helps me to earn more money that I could contribute.
Some of us value and need things that consume a lot of time...that's the problem.
