Allowing for the OP who makes braindead cocker spaniels look like
rhodes scholars. The subject is a fair one imo. FBW is nice but if you
ain't running enough redundancy to make NASA happy I wont trust it.
This train wreck proves the point...that or they were running Win 3.1.

The specific modes don't matter. What matters - the ONLY thing
that matters in this sort of discussion - is whether or not the
failure in question is survivable, and the likelihood of the failure.

And those "things that go wrong" can kill you, just as dead as
if the failure had been due to software inverting the plane or
whatever.
The bottom line is always going to be: I get on the plane, I have
a 1 in N chance of not surviving the trip. N is presumably a fairly
large number for ANY sort of control system which has been
accepted for use in manned aircraft - or any other sort of vehicle
- but if it's 1 in 10,000 for a mechanical system, and 1 in 100,000
for whatever alternative I'm offered (whether that alternative is as
easy for *me* to understand or not), the choice is pretty clear.

and that is precisely why I always feel it is the safest to fly right after
a crash. I figure I've got 999,999 more take off and landings before that
magic number comes up again.

There is a certain related argument and some humor that involves the same
error about conditional probability.
Unfortunately, I can't really post it. Using a certain word that begins
with B together in a sentence with a certain word that begins with A, even
for mathematical illustration, may very well attract the attention of some
government entities whose names begin with F, T, and/or D.
Because a certain category of illegal activity beginning with T is such a
hotbutton these days ... I just can't go there, even in the most benign of
mathematical examples.
