It gives me great satisfaction to see those two names separated

Or was that a negative sign? {8-]

I currently view this approach as more likely than a multigeneration
The multigen ship is only if there is some unforeseen reason why the
singularity and general AI is impossible. I cannot currently imagine
a reason why these concepts would be impossible, but I will allow
that there could be some fundamental reason why the singularity is

No, not out of the question. But you may know that my minimalist
approach to space travel comes from a background in weights
engineering, which asks the question, "What is the very least we
can possibly take and still get this mission accomplished?"
I will not kookify myself with further elaboration, but
it is in the archives, under Mars missions, about 3 yrs ago.

We can do with waaaay less than 160 people, and must. The
reasoning behind needing 160 is invalid in my opinion. A
practical multigeneration mission would likely carry 6 to 10
meat-based intelligences alive at any one time, and even then
the engineering challenges are daunting indeed. spike
