I am just concerned about every aspect of humanities viability.I first became interested in these issues ("1991") after discovering the potential social changes a technology such a "molecular nanotechnology" could present in the near (50 years) future.  I am new-to and therefor some what internet-illiterate, and will need time to get my message organized. I have not had much success in meeting people I.T.R.W. with similar interests. I hope my internet travels will be different.
