[ExI] Need creative help

Well, get as far as you can.  Either the Singularity won't happen that
quickly after all, meaning there will be more need for this than you
thought, or you'll have done part of the AIs' work for them: even
post-Singularity AIs can't simply snap fingers (or equivalent) and
make this happen instantly, so the solution will happen incrementally
faster for what you did before the Singularity.

If Gary Oleson still joins these discussions, he may also have relevant memories. The key person on the NSI side was Carol Rosin, whom I remember quite well from about four connections which immediately come to mind. (JUST now, I searched... she still has a big web presence; it says she is 82 years old now. Merger was intended to bring greater strength through greater unity, but opening to a larger constituency can sometimes dilute focus. O'Neill had a clear vision, and it is sad how it is not so visible to the world now as it was then.
