The problems that make shipping risky
Manual review takes hours. Critical issues get missed under deadline pressure.
Linters and static analyzers don't understand what your code is trying to do or why patterns are risky.
A Python security issue looks different from a C memory bug. Most tools treat them the same.
More code is being written faster than it can be carefully inspected.
Not everyone knows what to look for. Experience gaps create security and reliability holes.
Feedback buried in comments is hard to track, prioritize, or act on systematically.
