William,

I'd just like to offer an addendum to this post, as I wrote it
right after waking up and was somewhat groggy. As a side note,
I've just moved within the last two weeks from Boston to Perth,
Australia and my sleep schedule is still pretty hosed.

It occurs to me that, for space-ship design, if one were to
discover an ecosystem of naturally evolved space faring life,
that might make for a more suitable ecosystem to use for
simulation modeling. In that event, your criticism would be
spot-on. It's a pretty outlandish suggestion, but one I've
proposed on prior posts to this list. So for completeness, I
thought I ought to at least openly recognize it as a counter.


Best,

Maynard
