I do think that there's a meaningful difference between writing code that was bad (which I definitely did and do) and writing code where I didn't know what each line did.
early on when I was doing iOS development I learned that "m34" was the magic trick to make flipping a view around have a nice perspective effect, and I didn't know what "m34" actually meant but I definitely knew what the effect of the line of code that mutated it was...
Googling on it now seems like a common experience for early iOS developers :)
