Putting functions in the wrong place is still a thing. Having to refactor or rewrite things because of decisions made at an executive level is still a thing. Over-complicating code has always been a thing, too. Admittedly, "Information Hiding" has only really been a thing since Parnas, but I think it's more true than not that most developers are making the same categories of mistakes developers have always made, and when new programming languages and paradigms are created specifically to avoid those errors, they bring with them new categories of errors. Syntactically, the majority of code today looks completely different from 50-year-old code, of course. But I'm not sure things have really changed all that much on the human side.
