It’s truly strange that people keep citing the quality of Claude code’s leaked source as if it’s proof vibe coding doesn’t work. If anything, it’s the exact opposite. It shows that you can build a crazy popular & successful product while violating all the traditional rules about “good” code.
When I used to contract code for some game engine stuff back in the 2000's early 2010's, that was essentially my working standard. Essentially gave a boiler plate terms of my work. I will make it work, I will get it done quickly, it will run fast BUT you will incur a lot of technical debt in doing so. In a games engine it isn't a big deal, you are essentially just pushing pixels around a screen in a sand-boxed system. "Yeah, the decompression system does some odd things with memory addresses but it is quick and plays nice with your streaming system. Just don't change the overall mapping too much and it should ship ok.". "In this level of your game, I have this explicit exception code that prevents that streaming system from booting out too much necessary data. Don't change this unless you want a headache"
I shudder to think of what that style of code would do in a work environment with serious consequences.
I suspect we will find out a lot more of this in the decades to come.
