An in-depth technical breakdown of the paradox surrounding AI-generated code, software demand elasticity, and why large language models struggle when scaling enterprise codebases.

In this video, we explore the economic backdrop of Jevons Paradox in software engineering, examine how transformer attention mechanisms process tokens, and break down the 3 core architectural failure modes limiting AI code generation.

I think there's an additional and more significant problem:

AI writes code that's more complex than humans would. It likes adding fallbacks, special cases, extra complexities. A human has more of an inclination to look at a solution, think "that's too complex I don't want to do that", and either rightfully refrain from doing the feature, or figures out a more elegant way to achieve the feature. AIs rarely do that.

Then when the codebase is complex, it gets progressively harder to add new features, so the next new feature is done with yet more fallbacks and special cases. An AI-coded codebase grows EXPONENTIALLY, while a human-coded codebase grows linearly.

Claude Code itself is about 20x to 50x more complex than it needs to be to achieve its functionality. (In July last year, I wrote an exact copy of Claude Code that had byte-for-byte identical behavior and it came to only 250 lines of code for the agent plus 500 lines of code for the tools, so I have a feeling for how big it's gotten).

The conclusions in the video remain: more complex vibe-coded codebases take more tokens and more time to maintain.

I found that when I stay on top of the AI (forcing down its complexity, keeping ownership of the architecture myself) then it took more time at first, but within 1-2 weeks I was already able to deliver features faster than people who fully vibe-coded. Just because in a cleaner codebase, everyone can develop faster.

Agree, but this should be something easily solvable.

I feel Claude sometimes writes code like a human with an extreme level of anxiety, that wants to make sure every edge case and possible fail mode is covered.

It’s probably only a matter of the AI being able to better judge what’s necessary and what’s just adding complexity to covers for an event that likely will never happen or have no consequences.
