This isn't at all clear to me. Consider the possibility that the universe is
dangerous place. Advanced technology societies may not wish to
announce their presence. If they are capable of building something
like Robert's proposed M brains, they might be able to do so quickly,
as in a few hundred years. The star would appear to wink out, at
least in geologic time. With sufficiently advanced technology, they
may be able to make theselves nearly invisible. spike
