Also, suppose that there are and will be 1000 singularitarian activists who can, together, increase the probability of a positive singularity outcome from 0.1 to 0.2, and you are average amongst them. The benefit that accrues to you if you spend time working with the singularitarian movement is then delta U * 0.1/10,000 = 10^(-5) delta U, where delta U is the utility difference between the expected utility of the life you will live conditional upon existential disaster (which won't occur for quite a while - at least 15 years from today) and the utility of the life you will live conditional upon a positive singularity outcome.
I doubt that anyone really has a utility function that supports a delta U of 100,000 times the typical utility differences in our everyday lives, e.g. 100,000 times the utility difference of spending money on a nice house, an expensive family, etc. Therefore the goodness of a post positive singularity outcome cannot incentivize the individual to bring it about, to the singularitarian movement has to rely upon people whose personal notion of goodness comes from being the kind of person who puts others before themselves, even in the face of criticism and ostracism from those others.
That is, unless there is some kind of reward/punishment precommitment going on.
While adopting a virtue ethic of being the sort of person who works against existential risk may result in ostracism IF you reveal it, if we assume that ostracism hurts efforts to reduce that risk then the rational thing for such a person to do would be to keep it to themselves.
But yes, it may happen that it would be rational to bring up such issues, get one (important?) person involved and motivated and simultaneously ostracize yourself from everyone else. Then you would need to be a person who cared more about others' wellbeing than what those people think of you. Which, IMHO, is pretty damn cool.
I've been talking to a variety of people about this recently, and it was suggested that people (including myself) might benefit from a LessWrong discussion on the topic. I've been thinking about it on my own for a year, which took me through Neuroscience, Computer Science, and International Security Policy. I'm hoping and finding that through discussion, a much greater variety of options can be proposed and considered, and those with particular experience or observations can have others benefit from their knowledge. I've been very happy to find there are a number of people seriously working towards this already (still far fewer than we might need), and their deliberations and learning would be particularly valuable.
This is primarily about careers and other long term focused efforts (academic research and writing on the side, etc), not smaller incremental tools such as motivation and akrasia discussions. Where you should be applying your efforts, now how (much). Unless there's a lot of interest, it might also be good to otherwise avoid discussions on self-improvement in general and how to best realize these long term concerns, bringing those up elsewhere or in a seperate post.
A few initial thoughts:
