@park_mikan 네..... 어떤 경위로 이렇게 되었는지 너무 알 것 같습니다.. 얘기하자면 좀 긴데..

@wapj2000 실험 좀 해볼까하고 스킬 만들고 그걸 플러그인으로 배포하는 연습 좀 했었는데, 여기에 삘받아서 전직원 AI Native 엔지니어 대모험하고 있고 이게 사업 아이디어까지 확장되네요..

Creating good ideas requires depth of understanding. If we fully automate our code review process, it'll be much harder for us to create the ideas that once took us there.
Because "it's not just one loop. When you review what's happening…you come away changed…and that understanding is what you take to the next loop, and the next, and the next."
"When you have rich conceptual structures in your head that you can fluently recombine really fast without going out to ask some agent or some human how it works, that gives you the ability to fluidly take creative leaps."
"And that's the human part of the work, coming up with the next idea and the next idea."

There’s a popular theory that AI will finally make formal verification mainstream because mathematical proof of correctness will be needed when machines write most or all of the code. But will this happen? Hillel Wayne is one of the best people to answer. Timestamps:

Two things I found especially interesting, talking with Hillel:
1. Amazon used TLA+ to find a bug almost impossible to locate without formal methods.
In the paper How AWS uses formal methods, the AWS team shared that they’d found a complicated bug for which the shortest error trace to exhibit was 35 steps (!!). The bug passed unnoticed through extensive design review, code reviews, and testing. AWS concluded they wouldn’t have uncovered it if they’d stuck to conventional testing approaches.
2. Why not use formal verification for everything, then?
It’s because specs in the real world are a nightmare to write. Even a simple problem like “find the file in a directory that has the most lines” gets complicated when modeled with formal methods. We would have to answer questions like: ‘do we look at ASCII or UTF-8 new line characters, what about unreadable files, and Symlinks?’ Without formal methods, we can write a simple verification that is right in 99%+ of cases. Formal methods require a lot of extra effort for the less than 1% of exotic use cases!
