This, 100x.

I do M&As at my company - as a cto. I have seen lots of successful companies' codebases, and literally none of them elegant. Including very profitable companies with good, loved products.

The only good code I know is in the open source domain and in the demoscene. The commercial code is mostly crap - and still makes money.

This kinda puts it in words, most of us naturally expected 2025- LLMs to be able to generate OSS / demo / high craft code. Not messy commercial one.
