The first time I built a freestanding bookshelf, I put a lot of effort into making the feet level and the back straight and at a right angle to the feet. Once I put it up against the wall I'd built it for, I realized I'd solved completely different problem than the problem I really had. I needed crooked bookshelf, since the wall was totally tilted.

In the end I screwed some wall shelves in and called it good enough.

One of my first real DIY projects during a summer in college nearly 20 years ago was replacing the rotted out basement bulkhead doors on the ~120 year old house I grew up in. I took measurements of the old ones, bought some nice tongue-and-groove cedar and high-quality hardware, and built the new doors in the garage. When they were fully assembled, I carried them over to install on the old stone frame. I took off the old ones, put mine in their place...and they didn't fit properly at all.

Momentarily baffled, I realized that, despite appearances, the old frame was actually not square, in fact it was a parallelogram. I'd measured the height and width and assumed it was square. The previous (experienced) carpenter who'd built the doors I was replacing had clearly noticed this, and simply allowed for the misalignment in his design. He built perfectly square-appearing doors that mounted to the not-square frame. I had to go back and rework mine considerably for them to fit without looking ridiculous. They're still there and holding up well, but I also still think of this lesson on a regular basis in my day to day life now.

I feel this in my soul. I thought I could replace a door in a day, but months of fiddling, I discovered by frame is not only a parallelogram but it literally shifts by over an inch between seasons. (~100yr old house 2nd floor)

I recognized this submission from its title but did not remember what it was about. For some reason this anecdote reminded me. Yes now I know it's about the man who built staircases with his father.

I can never look at staircases the same.

Really generally shitty collision detection and detail. It's just that when you notice, it rolls back and adds resources until you think it's fine.

This sentence is the exact reason laying people off and replacing them with AI doesn’t work.

In the spirit of the article, what detail in the decision making of layoffs might you be missing?

I expect there's a lot of detail that I'm unaware of relating to running a company (planning; risk; legal; ...) that might make a decision foolish to me, but make sense if given more context.

The fact that machine learning can learn highly detailed patterns is the very reason why AI is so useful. So what you’re saying doesn’t really make much sense

AI doesn't deal with reality, it deals with tokens. This is why all those vibe-coded harnesses, little more than glue between various text IO interfaces, are several hundreds of thousands of source lines of code.

It's why a SOTA model took 100kSLoK to write a C compiler to compile one specific project.

It's why, when I asked for a simple markdown -> ansi escape codes converter (for terminal output) in Python, SOTA Claude and SOTA ChatGPT both give me +- 150 SLoC when my own LUT-based version came to under 10 lines of code + a LUT.

Reality has a surprising amount of detail, but LLMs don't exist in reality, they exist in a virtual world made up off tokens.

Do you exist in reality? Or just in a virtual world made up of sensory signals? Do you have access to the Ding an sich any more than a (multimodal) LLM?

Reality does not have amount of details, it is infinite in all directions. Its only that we perceived certain amount of details, some more some less. One can spend their whole life mastering a single aspect and there always will be room to improve.

This has always been the fun part of programming to me. I know most people hate it, but I really don’t mind being on-call (ok I hate being woken up) and fixing weird bugs that users run into. All these small edge cases that people run into because reality is odd. Of course I’m in scientific programming so that probably colors my view.

It’s always a little disappointing to me when I think I’ve run into something unique but it ends up being user error or something.

I echo this. The kind of entropy that real users bring has been refreshing to face as a founder.

Being a founder has a lot of SRE like activities. Fortunately I used to actually like troubleshooting and hence love being a founder but I know a lot of people quit this path because of the "suprising amount of details" in reality!

Base I what is the level of detail to reality suprising. To me suprising means mysteriously or improbably unexpected. Why should we expect reality to be simple. Note complex and simple are somewhat subjective. The human brain evolved to just sufficient baseline level be able to handle the level of complexity of reality. So why would it be unexpected that humans find realty complex when our brains are calibrated just enough to handle it.

a good read indeed! Makes me think about my use of coding agents differently, as the main thing they do is deal with a lot of details that matter to the execution but don't matter to me personally enough to figure them out. Would love to see this author's more recent take as this was written pre-LLMs taking over the world.....

That sort of abstraction has always existed, it's just been a matter of hiring experts or labor from other humans. Reality still has a surprising amount of detail. You deal with it by engaging directly, delegating to someone else to engage with, or just brute force your way to a crooked staircase.

When you hire someone to work on the stairs for you, you /hope/ they know what they're doing, especially if you don't have the skills yourself to judge their work. Same for an agent.

An ancient article that now looks even cheesier. It's so hard to make those goddamn stairs. So complex, such wisdom.
