Thinking In Systems: A Primer by Donella Meadows
My 17 year old son bought it for me for my birthday. I've been enjoying it a lot. I do in fact like thinking in systems and learning more about it, and reading it in a more generalized fashion than I tend to in the computer science world has provided a refreshing perspective. It's all very approachable, nothing very complex, but gives names and discreet patterns to things I intuitively understood but previously wouldn't articulate easily. Definitely one of my favourite gifts in a long time.
Stories of Your Life and Others by Ted Chiang
I read bits of this to my wife at night occasionally. One of the first trips we went on together was camping on a little island, and I had Kafka on the Shore (Haruki Murakami) with me which I suggested I read to her in the evening. She really liked it and I've done it since. I wish I did it more often. Anyway, Stories of Your Life and Others is a wonderful collection. I've read it a few times, not always completely, and I enjoy it. Story of your life is the standout. It's what the movie Arrival is based on, which I consider one of the best scifi movies of all time. It's a beautiful story.

I've been watching the show and decided the books deserve a shot. If the show is as good as it is, the books must be great, right?

> Thinking In Systems... gives names and discreet patterns to things I intuitively understood but previously wouldn't articulate easily
I liked the observations like:
'long-term behavior provides clues to the underlying system structure. And structure is the key to understanding not just what is happening, but why'*
'Purposes are deduced from behavior, not from rhetoric or stated goals.'
'Large organizations of all kinds, from corporations to governments, lose their resilience simply because the feedback mechanisms by which they sense and respond to their environment have to travel through too many layers of delay and distortion.'
* 'Structure generates behavior' as stated in the video: https://www.youtube.com/watch?v=o-Yp8A7BPE8

This book made me start focusing on flows vs stocks, a distinction humans tend to get backwards and the make several related mistakes. The book gets some valid criticism, but it's a primer and a good one at that.

> Purposes are deduced from behavior, not from rhetoric or stated goals.
A light rewrite of the slogan "the purpose of a system is what it does".
I hate that slogan. It's supposed to be profound, but it's actually really, really dumb.
The whole point of the word purpose - its purpose if you will - is to be able to talk about the difference between what a system does and what it ought to do. To say the purpose of a thing is what it does, is to render the word completely redundant.
If the stated goals of a system don't match what it does, then either you have a dysfunctional system that needs to be fixed, or those stated goals are lies.
In these days of AI, it's all the more important to think clearly about purpose. Just because a system does a thing, there's not necessarily anyone who wants that thing. And there's definitively not any "spirit of the corporation" or "spirit of the nation" or "spirit of the language model" which wants it. Only persons want things.

If it bothers you, you could work around the semantics and talk about its empirical purpose or observed purpose, vs intended purpose, rather than using purpose and expecting it to be interpreted in a particular way.
I think the jarring alternative definition of "purpose" is an intentional mental hack: to break people out of orienting themselves around design intent, when processes often go out of alignment with that. It's easy for humans to fool themselves. Taking a dispassionate, empirical view when considering what a process is doing, or analyzing what its range of behaviors is, can illuminate many problems.

I’ve always interpreted this saying to point in the direction you’re actually going. That a machine does not have a “purpose”. Its creator might have had a purpose in mind, but when talking about the machine one should focus on what it actually does. This avoids needing to fend off attacks about how noble the creator’s intention for their machine may or may not have been, which could otherwise consume the rhetorical oxygen better spent.

> or those stated goals are lies.
Yes, that's part of the point. If the stated purpose of a system is to "improve vehicle fuel efficiency" but the observed behaviour is to give car companies a way to avoid doing much of anything about fuel efficiency, or if the stated purpose is to "encourage EV adoption" but the observed behaviour is "funnel money to certain rich people" then you are better off assuming that the behaviour you observe is the intent, and the publicly stated purpose is marketing spin.
On the other hand, things change over time. Google started out organizing the world's information, and gradually turned into surveillance advertising. They got rid of "don't be evil" so there are no explicit lies. They aren't a dysfunctional search company, they are a functional surveillance-advertising company, that thing they do - update your expectations so you believe that's their purpose and don't believe that they are "trying to be good but misguided".

They do not need to be lies, but they may be. They may also just be a mismatch between the level a statement is generated at and the level it is consumed at, the “level” here being something we could call a system’s functional context.
Additionally, a statement is generated by a system and reflects itself a separate purpose in its generation. A system can exist without statement of purpose, so why was it made? The statement has an intent and an audience. It is therefore necessarily more constrained than the system itself, and for the systems we are referring to, it is markedly less complex than the system itself. It cannot hope to capture the full function, which is what can serve (or not) a purpose.

The quote you replied to is used to educate a reader how to understand an existing system. For example, it helps one understand why a system is in a state when as you say 'there's not necessarily anyone who wants' it that way. Rivers are polluted because there are some factors in the system which enable it.
Also, as the video I linked in the previous comment says: 'our first instinct is to blame people in the system and that is a low leverage response...actions people take are possible, feasible, and rational because of the universe in which they exist.'
I am not sure if you've read the book. But even though you've not used terms like feedback loops, etc. I think what you are saying is not much different from what the book says.

I think you might like this song then: https://www.youtube.com/watch?v=nqBBNjkAlXM
as it takes normal every day systems that we think we can depend on (banks, the army, phones) and sarcastically highlights some of the worst things those systems do vs what we're told they do. The chorus is that slogan.

Chiang's stuff is fantastic. I'd love to live in a timeline where he writes novels instead of just short stories, but I'll take what I can get. (Big fan of Arrival, too -- even hit the GitHub repo of all the glyphs and got one tattooed.)

If you loved Thinking In Systems: A Primer, you may want to read Business Dynamics by John Sterman [1], one of the proponents and pioneers (after Jay Forrester) of systems dynamics. It's a textbook, but even so it is readable and engaging.
Systems thinking changes the way people think about solutions, often for the better (but not always). There's a tendency to think: "uh... it's the system, nothing's gonna change unless we change the _system_ per se". And that's correct. But individual actions also change systemic outputs. So. Case in point: climate change and all that...
[fun fact, I took a class with Sterman at MIT. He's fantastic, very engaging!]

Can you tell me more about reading to your wife? Is she listening intently, or like falling asleep? or is she doing something and listening in the background? (knitting / on her phone)

A bit of intent listening and a bit of passing out, depending on the mood and day. I have reread many pages due to her passing out without me noticing.
I also read to my youngest perhaps 5 days per week, and used to read to his two older brothers for many years. I’m realizing I spend a lot of time reading to people. They definitely fall asleep quite often.

Not the OP, but my partner and his wife have done this for years.
I was inspired, and I did a variation of it with a partner at one point. It was really nice. Feels kinda like a synthetic version of an engaging conversation with someone you care about, but perhaps with words you can't muster yourselves at that time of the day. If you've chosen the book together, it's guaranteed to be the right thing between you. It's nice to feel like you're hearing or learning something interesting from the person you care about, even when one of you perhaps don't have the conversation or the story in you. (I have a high appetite for connecting over ideas, but sometimes people I care about can run out of capacity before me, so it feels like a hack for my relationships.)
I imagine swapping reader-listener roles is another variation.

To me, Systems Thinking material always reads as if written by philosophers who wish they were engineers.
