I transformed the Plush interpreter from a stack-based design to a register-based architecture, and the performance boost was more than I expected!

@gkozlowaski Also not sure businesses are gaining much by taking said risky bet. I'm seeing a lot of likely vibe coded bugs, not a lot of actual software improvement.

[Maxime Chevalier @Love2Code]

I've been reviewing a lot of code written by Opus 5.5, and it still seems to make a lot of bad software engineering decisions. The kind that will accumulate/calcify into unmaintainable software over time. IMO even the agents will struggle to maintain vibecoded software.

@brinkzapp I was programming before you were born, kid.

@valigo Like some invite to try their game? They're probably hoping you'll tweet about it

@th1agofm Sort of. I've had CC implement web software and found later that it had decided to not gate certain endpoints based on user login. It just decided that data ought to be public I guess, and never told me. You can easily fix the code, but leaked data can be more problematic.

@Luiz0x29A @siematos lol.

[Maxime Chevalier @Love2Code]

@preshing I found that the code quality coming out of GPT 6.0 sol was so awful it was just... Objectionable... Then they released 6.1 a week after, like they knew something wasn't right. They immediately yanked that model 😆

@CustomWetware @shlokbuilds That's what I would expect to happen. Imagine having five humans with almost no coding experience maintaining a massive codebase using only AI agents.

[Maxime Chevalier @Love2Code]

@th1agofm What did you build at 100M LOC?

[Maxime Chevalier @Love2Code]

Claude Code ported my GLB mesh loader and skeletal animation code from Plush to Rust in all of 5 minutes... That was... faster than I expected.

[Maxime Chevalier @Love2Code]

@davidmanheim @ZackMaril I agree for toy apps and throwaway scripts it's great for sure.

[Maxime Chevalier @Love2Code]

@dtcb Try that with an operating system

[Maxime Chevalier @Love2Code]

@siematos Rewriting a single function is one thing, rewriting an entire large piece of software with nontrivial integration is much harder. Also, even at 10,000 tokens per second, you're still outputting what, 40 kilobytes of code per second? That's assuming *zero* reasoning tokens.

[Maxime Chevalier @Love2Code]

@siematos IMO that's the wrong take. Code is *cheaper* (still not free), but good design takes time to happen. You need several iterations, lots of testing, bugfixes. If you try to just entirely rewrite a large/mature piece of software, you are basically guaranteed to introduce issues.

[Maxime Chevalier @Love2Code]

@ZackMaril Some of it is small things like variable/method names that are not descriptive or appropriate at all. Some of it is poor factoring of logic, with a lot of stuff happening directly in main, and other things kind of spread into multiple files.

[Maxime Chevalier @Love2Code]

@tetsuo_cpp Musk-style leadership, where he calls the shots on everything, and often makes decisions without thinking through the implications.

[Maxime Chevalier @Love2Code]

@__ALEZ I like your custom UI language. Looks cool :)

[Maxime Chevalier @Love2Code]

@ara3dstudio I have the prefabs working near the end of the video!

[Maxime Chevalier @Love2Code]

Had to show you this one because I think this is genuinely cool. My WIP networked 3D engine that runs in a browser. Also demoing live-editing the world, and prefab objects! :)
