Well, I just used a contrived example to illustrate my point.

You would be well served to review the code. I don't usually need to do much of that since I work with models edit by edit, with every single line they write approved by me.

You would be surprised at all the errors even Claude Opus 5.5 commits. Not syntax or even basic logic errors, but more insidious errors that betray a lack of being able to see the bigger picture, or serious architectural errors.

If you want example, I have them in abundance. These models still need serious supervision. Unless you are spot checking the code deeply, you won't notice.
