Excerpt about the Electric Monk from Douglas Adams's "Dirk Gently's 
Holistic Detective Agency":

When the early models of these Monks were built, it was felt to be important
that they be instantly recognizable as artificial objects.  There must be no
danger of their looking at all like real people.  You wouldn't want your
video recorder lounging around on the sofa all day while it was watching TV.
You wouldn't want it picking its nose, drinking beer and sending out for
pizzas.

So the Monks where built with an eye for originality of design and also for
practical horse-riding ability.  This was important.  People, and indeed 
things, looked more sincere on a horse.  So two legs were held to be both
more suitable and cheaper than the more normal primes of seventeen, ninteen,
or twenty-tree; the skin the Monks were given was pinkish-looking instead of
purple, soft and smooth instead of crenellated.  They were also restricted
to just the one mouth and nose, but were given instead an additional eye, 
making for a grand total of two.  A strange-looking creatre indeed.  But
truly excellent at believing the most preposterous things.

--- End of excerpt ---

To summarize what the electric monk is ... it is a device built for the 
purpose of believing things to save you the tedium of believing all of the
things people are expected to believe.  The description of the monk in the
above excerpt implies that we, terrestrial humans, are descendants of these
electric monks.  The physical description fits us* and also because we do seem
to be pre-programmed to believe all sorts of preposterous things.  Even 
carrying contradictary beliefs.

*: Physical description:  Well, okay, it fits caucasians.  Mr. Adams could
have taken a moment to consider that most humans' skins are shades of brown.
But I guess that's besides the point of this post.

The book really isn't about this monk, I don't think any summarization of
the book, or it's sequal "The Long Dark Teatime of the Soul", would even
mention the monk.  He's just a side character that pops in and out at various
points.  

It's still a prime example of Douglas Adams's unique way of writing which 
makes a big, obvious point, while also making a subtle less obvious point at
the same time.

It doesn't seem like a subtle point in this phlog post but that's because
this excerpt is focused on this point.  Starting from the beginning of the
chapter, by the time you get to this excerpt, you already have firmly 
planted in your mind an image of a robot, maybe Bender from Futurama, sitting
on a bored horse, atop a hill looking down in a valley, unable to move because
it believes (wrongly) the entirety of its surroundings, and itself, to be a
uniform shade of pink, thus making it impossible to distinguish one thing
from another.

So you are also picturing everything being pink even though the author
explicitly said that is not the case, it's just a false belief the
malfunctioning electric monk held.  Once a mental picture is painted, it
can be very difficult to unpaint it (or, more accurately, to paint over it).
This small excerpt isn't quite enough to do it unless you're paying special
attention to it.

Another good example of this is 42.  People say that according to the 
Hitchhiker's Guide to the Galaxy: 42 is the meaning of life, or the answer to
life the universe and everything.

However, this is not true, strictly speaking:  42 is the answer to the 
ultimate question of life, the universe, and everything.  So it's only the 
answer to another question.  Now you have to ask "okay, so what is the 
*ultimate* question of life, the universe, and everything".  

And ... *** spoiler alert *** ...

One such possible answer that came up, finally, in the Hitchhiker's series was
derived (in an almost divination sort of way) out of the protagonist's 
subcontious mind: "What do you get when you multiply 6 by 9".

So the obvious point here is that the ultimate question isn't anymore 
"ultimate" than any other question.  In-fact it's sort of a boring, meaningless,
question unless your life depends on knowing that answer for some reason.
But if you stopped reading here and thought for a moment you'd realize (if you
remember your multiplication tables) that 9x6=54, not 42.

This means that, not only did this great and powerful computer come up with a
stupid question to fit the bill of "The Ultimate Question of Life, the 
Universe, and Everything", but it didn't even get the answer right, a simple
multiplication.  Or it got the question wrong.  Or both.

Someone, reading this in the 80's, might think that's preposterous.  How can a 
computer be so bad at math?  But now we have LLMs and we know how bad a 
computer can be at math and answers and questions.
