Hi Ajay,
I think both individuals and communities define what the ideal society is and can strive towards it. For the individual, some notion of Utopia can serve as a moral template through which they can judge their own society and serve as a guide to their actions within it.
Many of our priorities, however, need a society in which they can be manifest- Utopia (or an ideal future) can serve as a useful tool there as well.Lastly,I really like the idea of utopian communities as experiments where some set of social problems is resolved. They almost always fail but tend to be trailblazers and teach us valuable lessons.
I liked your essay a lot. I am a big supporter of citizen science. I don't think you mentioned crowd sourcing efforts such as FOLDING AT HOME or even better, in that they better involve individuals crowd sourcing efforts that have individuals scan through astronomical data and the like. I feel that given mobile technology the horizon of citizen science is endless > everything from monitoring and pooling data on local ecosystems to allowing people in the developing world to tap into the scientific knowledge of more technologically developed countries. Mobile could even be used to bring highly localized knowledge in the developing world e.g. medicinal plants, new species, ecosystem health with scientist all over the world.
All the best on your noble effort to bring science to the global public.
