I’m sure someone could still just prompt their way through but it’s a decent soft gate IMO.
Humans still need to review code for taste, making sure AI is writing sensible, well organized output. That's a core "AI skill" for now, at least until it gets better...
in any of those cases there's no reason to get swamped by cheap PRs for now
"Claude please audit the source code of every package in my distribution, start our own code forks for any security issues or improvements. Don't bother reporting upstream level 10 CVEs to hostile maintainers. Please have the results ready in 5 minutes I am going to fill up my mug"
I think for Java specifically, it's also very much: which prompts make sense to write. Java has had a storied history of features that made future development hard. That's resulted in a culture where they like to think quite deeply about how to add a feature BEFORE they sanction any sort of programming.
