Technical, cognitive, and intent debt

I see what Martin is saying here, but you could make that argument for moving up the abstraction layers at any point. Assembly to Python creates a lot of Intent & Cognitive debt by his definition, because you didn't think through how to manipulate the bits on the hardware, you just allowed the interpereter to do it.

My counter is that technical intent, in the way he is describing it, only exists because we needed to translate human intent into machine language. You can still think deeply about problems without needed to formulate them as domain driven abstractions in code. You could mind map it, or journal about it, or put post-it notes all over the wall. Creating object oriented abstractions isn't magic.

Hits the spot for me. I am always pushing back on AI to simplify and improve concision.

LLMs don't lack the virtue of laziness: it has it if you want it to, by just having a base prompt that matches intent. I've had good success convincing claude backed agents to aim for minimal code changes, make deduplication passes, and basically every other reasonable "instinct" of a very senior dev. It's not knowledge that the models haven't integrated, but one that many don't have on their forefront with default settings. I bet we've all seen the models that over-edit everything, and act like the crazy mid-level dev that fiddles with the entire codebase without caring one bit about anyone else's changes, or any risk of knowledge loss due to overfiddling.

And on Jess' comments on validating docs vs generating them... It's a traditional locking problem, with traditional solutions. And it's not as if the agent cannot read git, and realize when one thing is done first, in anticipation of the other by convention.

I'm quite senior: In fact, I have been a teammate of a couple of people mention in this article. I suspect that they'd not question my engineering standards. And yet I've no seen any of that kind of debt in my LLM workflows: if anything, by most traditional forms of evaluating software quality, the projects I work on are better than what they were 5, 10 years ago, using the same metrics as back then. And it's not magic or anything, but making sure there are agents running sharing those quality priorities. But I am getting work done, instead of spending time looking for attention in conferences.

This lines up with YAGNI, but most people believe the opposite, often using YAGNI to justify NOT building the necessary abstractions.

The counter-argument is that people build abstractions they deem necessary but aren't, and then they're married to that premature architecture quite often. That's what YAGNI is there to advise against.

I don't think what Fowler says here is in favor of saddling the early versions of your system with abstractions before you actually seen its use in practice, and its needs over time as requirements and conditions change.

From this "Laziness drives us to make the system as simple as possible (but no simpler!) — to develop the powerful abstractions that then allow us to do much more, much more easily." it's clear that when he talks of abstractions he means of very basic, and as simple as possible, building blocks. Like having core, orthogonal, principles in the system.

Not the kind of piling of software and pattern design abstractions e.g. the Java land in the past used to build.
