Actually, the most annoying but important thing is
testing, I think.
Things that we should have taken for granted in that process,
or things that were missing, if we keep checking them,
the test cases keep increasing.
To some extent, the level of what's just natural
seems to be progressing very well thanks to AI.
Now it even does testing on its own.
Thanks to that, I still have a hard time coming up with strange test cases,
but for the most part, it seems to have become much easier.
