Absolutely agreed. If your code line by line isn't clear, then the code is the problem.
Commenting before a block of code (a function / algorithm or whatever) explaining what it is meant to do, absolutely that's great though, saves time when revisiting.
My take is that no matter which language you are using, and no matter the field you work in, you will always have something to learn.
After 4 years of professional development, I rated my knowledge of C++ at 7/10. After 8 years, I rated it 4/10. After 15 years, I can confidently say 6.5/10.
