With open source decompilations before AI, considering there are often a dozen collaborators working on the project publicly with their work done out in the open I can generally trust that multiple people went over most changes made to the project. With a vibe coded project, it's easy for one person to push 500,000 lines of changed code with a single update that would make the review process impractical at best.

I'd rather trust the dozen people who've been working on a project over 5 years than someone who got a Claude subscription, hammered out something in 2 weeks, got it working well enough for their own satisfaction, then abandons the project.
