Five years ago we had pretty good static analysis tools for popular languages which could automate certain aspects of code reviews and catch many common defects. Those tools didn't even use AI, just deterministic pattern matching. And yet due to laziness and incompetence many developers didn't even bother taking full advantage of those tools to maximize their own productivity.
The devs themselves can still be lazy, claude and copilot code review can be automated on all pull requests by demand of the PM — and the PM can be lazy and ask the LLMs to integrate themselves.
And the LLMs can use the static analysis tools.
