Based on past writings of all three, I've come to the
conclusion that (unlike some people I've met over the years)
they can be trusted to know (and not exceed) the limits of
their own knowledge and expertise.  IOW, they know what they
don't know.  So when they make a statement I give it
considerably more weight than I would most people.  There are
certainly areas in which they aren't authorities, but you
don't catch them making statements in those areas as if they

There are other people I know who are probably just as
intelligent and just as expert (in other fields), but when they
get to the edge of what they know, they don't stop talking.
They either don't know (or won't admit) what they don't know.
AFAICT, they apparently just make up stuff in order to have
answers to questions.  Does that make sense?

All that aside, I don't know that I could win an argument with
them even if I was right and they were wrong.  ;)
