As an engineer who bills by the hour, I like how LLMs are affecting codebases.

I've been preaching the benefits of well designed code for a long time, explaining that 10x engineers exist but only if the codebase permits... Nobody got it. Now when people start with a poorly architected project and the AI starts generating slop code on top at a rapid rate, they finally learn the lesson I've been trying to get across. The effect was always there but AI makes it even stronger and allows people to understand the problem of compounding technical debt faster.

I genuinely feel that companies with existing well designed systems with intentional architecture and design patterns will have far more leverage, with AI coming into the picture - as opposed to upcoming systems which are vibe coded from day 1.

Conversely, it is a pleasure to watch an LLM effortlessly extend a well-built code base in the existing style.
