I had similar experience early in my career and now have another.
I worked on a banking application where I needed to calculate APR (annual percentage rate). I asked several mortgage bankers how they do the calculation, not a one knew. Each stated the rate was on the docs they received from the intake clerk. I asked the clerk, she said she used her mortgage calculator, a hand held device.
Currently, I am investigating solar panels for my home. I have 4 companies responding each with proposing different configurations despite using the same utilization rates published by my electric provider.
Accuracy, it appears, is in the math of the beholder.

I didn't intend to imply otherwise, despite the overarching topic. I switched gears.

We've been building physical structures for thousands of years, and writing software for less than 80. Architecture and civil engineering are obviously more mature disciplines than software engineering. Assuming civilization survives, I am certain that our software development efforts will be viewed by future engineers in the same manner that the builders of mud huts are viewed by modern civil engineers.
(But we do build some very impressive mud huts!  )

Software techniques will undoubtedly improve, but there are things from 45 years ago that I don't find primitive. I think software will always be difficult because, unlike engineers, we continually evolve existing products and, unlike mechanics, we repair them while they are up and running.

I think you are giving too much credit with the "mud". Mud + straw bricks will last a very long time!
More like straw huts with a few sticks.
This is making me think of software before memory protection.
I imagine a village with thatched roofs side by side by side.
Each house is an app. The thatched roofs are the ram for that app.
The village is the whole machine.
A fire in one house would rapidly jump roofs and take out the entire village.

Yes, in the right climate. It is not well suited to climates with heavy rains.
This is beside the point. No modern architect would seriously consider using mud (or mud + straw) for a building, and likewise no future software engineer would think of using the techniques (or lack of them  ) used in most current software.

Clay is actually a very good building material and it's used occasionally to construct ecological buildings. See for example Clay Houses - Resilient Fireproof Unique and Attractive[^]
That said, it's advantages are so impressive that it's hard to understand why it's not used more widely.

Do you mean raw clay, or baked clay? Raw clay tends to go soggy when wet...

Not baked (as in bricks).
When building a structure, the clay needs to be wet so it merges tightly with the rest of the material and pores get closed. It needs to dry for quite some time, so you might run into trouble building large structures unless you can be very sure to have a long period of dry weather.
I know it works pretty well because my brother used clay (pellets) and straw to replace the walls in his studwork house. No problems with soaking at all.

Don't worry. I'm not an expert, but I guess that our ancestors took ages to learn why some 'mud' huts lasted forever while others melted away in the very first rain storm.

But we do build software that keeps aircraft in the sky (that's a system failure, arguably, but involves the software), keeps nuclear reactors from melting down, and calculates dosages for medical devices...
I've developed software that is currently flying on passenger aircraft and I can tell you with certainty that the practices and processes used for those lines of code were vastly different than what's used for most software - the NASA Software Engineering Handbook is a pretty good example of this.
Java, Basic, who cares - it's all a bunch of tree-hugging hippy cr*p

Don't even get me started on the dosages one. A multithreading issue killed 3 people (as i recall) connected to machines delivering chemo treatments.

Air traffic control, aircraft avionics
Medical equipment
Law enforcement communications
Defense electronics and C3I
Manufacturing controls, especially for food and medication
...
All of these applications and many more have profound human health and safety implications.
We build much more than bridges and skyscrapers.

I agree.
And have done since the The Beginning (Turbo Pascal 5.5 and Turbo C++ 1.0).
No language should be purely OO, multi-paradigm (ptui) is the only true path.
Use OO when it makes sense, but not wen it doesn't.
You're not alone out here.

I find it interesting that you now use objects less than when you first started to code. I would've thought that it would work the other way around. But maybe that's for us dinosaurs who first learned structured programming and later had to think in terms of objects. If you learn objects first, I can see it progressing in the opposite direction.
I'm curious as to what you meant by C++ changing your attitude towards objects. Maybe you started to use them less because C++ has too much boilerplate!
Sure, a standalone piece of code will be smaller, faster, and easier to understand if it isn't broken up into many little objects. But you called it a "little HTTP server". What if it had to be big? Or support other protocols? Or be integrated with a large system?
The larger the system, the more important it is to achieve reuse and abstraction, which means separating concerns and using polymorphism, inheritance, and encapsulation. Without this, developers clone and tweak code that can't be reused because it's admixed with other concerns. It also becomes harder and harder to add new capabilities, because they have to interwork with components that exhibit superfluous diversity. A maze of twisty little passages, all different.
That said, OO can get overused and won't solve everything. It would be great if it could be coupled with aspect-oriented programming, but I haven't seen a good way to do that, and aspects may simply be intractable when it comes to cleanly separating concerns.

I can't really find much to argue with here, as I do believe OO has its place, even if i wonder if it hasn't made a mess of things too.
I moved away from objects with C++ once I learned STL which led me to generic programming which deals in aspects moreso than objects.
