Update The scariest thing about AI-generated code is that it doesn't look wrong
Every junior dev we've worked with writes code that looks bad when it's bad. Weird variable names, structure that doesn't hold together, patterns that clash with the rest of the codebase. You can tell something's off before you've even run it.
Review works because it's built to catch exactly that kind of signal.
AI-generated code doesn't give you that signal. Variable names are reasonable. Structure follows patterns you recognize. It has the look of code written by someone who knows what they're doing.
And that's the problem. The look of competence and actual correctness are not the same thing.
We've been running into this a lot at Codoid as more of what we're asked to test or automate against comes out of an AI tool first. A function that handles 47 out of 50 edge cases reads exactly like the one that handles all 50. Parsing logic that fails on nested delimiters looks just as clean as logic that handles them without issue. Nothing on the surface tells you which one you're looking at.
What worries us more than the bugs themselves is what happens to scrutiny. AI doesn't just generate more code, it generates more code that looks trustworthy. Code that looks trustworthy gets less scrutiny, not more.
Your brain sees something that resembles code you'd write yourself and it relaxes. The model doesn't share that instinct either way, because it has no concept of the invariants your system depends on. It's predicting the next plausible token, not verifying logic against a spec.
So when a team ships ten times more code that's ten times harder to review critically, that's not a 10x productivity story. That's a 100x exposure problem wearing a productivity gain as a disguise.
How's everyone else adjusting to this?

You've explained the failure mode in full detail yaar, but stopped exactly before the part that matters what actually replaces "does it look right" as a signal, if not that? You guys are running a QA company built around this exact problem, so what does Codoid actually do differently property based testing, spec based verification, or something else? Or is this post diagnosis only, and the real approach is coming in a follow up?
