On the other hand we'll probably see a lot more fully vibecoded projects gaining traction, because of the rate at which they can move once human design and review gets taken out of the equation.

For example, I recently came across Hucre, https://github.com/productdevbook/hucre, which is a JS spreadsheet library apparently developed entirely in the past few months and which has already gained 2.2k GH stars.

Is it any good? Who knows, but the alternatives for spreadsheet handling in JS aren't great, either being limited, semi-commercial, or unmaintained. And creating a new one without LLM-assistance is a huge, painful, mostly thankless undertaking. It's not surprising that a zero-dependency option that promises to do everything this can do would be popular.

Everyone has had the experience of butting their head against functionality limitations of open-source libraries. Fully vibecoded libraries will be able to add functionality at a rate that human-authored ones can't. Code quality might suffer, but if a library has a feature you need, and you've got a deadline to hit, are you going to avoid using it? Is the average developer? Or the average LLM?

I think we're about to hit an interesting period of human-only projects competing with vibecoded ones, and it'll be an acid test as to whether the pro and anti claims about AI-coding bear out in terms of code reliably.
