[I really appreciate you sharing this. First off, congrats on getting HintWordly live! As a DevOps engineer, you’re probably used to seeing the "big picture" of architecture, so it must be really frustrating when the "micro-logic" of the code feels like a black box. This is the "hidden tax" of AI code. We save time upfront but pay it back with interest during debugging. It really reinforces the concern that I wanted to capture in this opinion piece, that is, the "ownership gap". This quote I heard from Andrej Karpathy perfectly described it: "We can outsource the thinking, but we can't outsource the understanding". Scaling and optimization are where the "vibe" ends and engineering begins. Thanks for reading and sharing such a relatable struggle, and best of luck with the refactoring!](https://hashnode.com/posts/the-vibe-review-trap-when-ai-written-code-becomes-the-death-of-deep-understanding/69f59df8ec32cba9e5be818a/comment/69f708b40ab374db9994df68#reply-69f7cc4976c1469ba4fb33fb)

[Agree. In the real world, you don't always get to work on a greenfield. Often, we have to maintain codebases that are years, if not decades, old. The erosion of the mental models required to understand complex systems could result in a complete collapse in maintaining those systems. If we treat code generation as a black box today, we’re essentially leaving a technical debt time bomb for whoever has to maintain it tomorrow.](https://hashnode.com/posts/the-vibe-review-trap-when-ai-written-code-becomes-the-death-of-deep-understanding/69f59df8ec32cba9e5be818a/comment/69f625a40ab374db99120dbc#reply-69f680a10ab374db99498b83)

[Exactly! That's the primary concern most developers overlook.](https://hashnode.com/posts/the-vibe-review-trap-when-ai-written-code-becomes-the-death-of-deep-understanding/69f59df8ec32cba9e5be818a/comment/69f63ced0ab374db99210542#reply-69f67d4a0ab374db9947ed22)
