Two things before I say anything else: Kenneth, great to see you on the DhO again! Daniel, I get the image of you in a Ron Burgundy-style get-up, complete with big 'tache, if you ever actually do any stuff on TV.
1) When the A&P to Dark Night transition is as well-known and accepted as being a normal part of human development, as is, say, PMS, and thought of in the same basic human sectarian terms, we will have done something good for the world.
I do think that a lot of headway has been made since the dharma-clusterbomb that is MCTB presented a no-bullshit description of what proper insight meditation entails. Just
knowing that this transition is typical of pretty much every effective spiritual model is a key to progress in itself, but I don't honestly know whether it could ever be viewed in sectarian terms without a massive shift in the science as a whole. I know there's an ever-increasing openness to this side of things, but the general pattern of how quickly changes in prevailing scientific paradigms go would suggest that we're looking at a good few decades before the radical perceptual changes possible through insight meditation are fully accepted and understood. It's not to say it won't happen, but I think the issue which is so glaringly clear to many of us on here, that a big "spiritual" experience is inevitably followed by the mental-shitstorm from Hades, would be rarely, if ever, considered by your average meditator who got into this just trying to be less stressed out.
2) When there is a set of basic attention training concepts and techniques that are part of mainstream education, like sports are (thanks to Kenneth Folk for his sports ideas: more on this to come), that will be real progress. How many kids could get off designer speed if we taught concentration and attention stabilization in school? I will bet a lot...
I would state quite categorically to anyone in the world that what is possible through meditation is far, far, far better and more satisfying than any drug whatsoever. End of story.
The idea of introducing these sorts of attention training techniques into schools is excellent, and may become more possible as the educational system changes in future; I encourage my daughter to work with her attention and to use it to cut through her own mind-stories, which she has confirmed to be effective, and without
any reference to Buddhism or any religious model.
3) When meditation and related skill-sets can be discussed just as what they are: things to develop and skill-sets, rather than in religious terms with all the inherent craziness that nearly always comes along with that, and not have the religious world freak out about them, such as it does with things like evolution and climate change and other basic scientific topics, that will be revolutionary.
I think that this is a very realistic possibility, but the timescales involved before it becomes as commonplace as, for example, NLP terminology, may be a little longer than we expect. I remain optimistic though, it's a wonderful thing to aim for and I think that the Hardcore Dharma movement could be instrumental in making this possible; many of us work in other mediums and carry our practice into everything we do, our interactions with others and the way these relationships develop could provide some unconsidered links which allow for this to become a reality sooner, rather than later.
Isn't it about time we had a revolution anyway?

I've got more I wanted to add but these are the bits that initially stood out to me, I think this is an excellent idea and wouldn't be surprised if this allowed for the development of both the wiki, the updated MCTB and any other projects related to Hardcore Dharma...all dependently co-arising.

Excellent, excellent stuff.
