I fully agree

The problem is that there are times we don't create good code, we create bad code in a hurry and comment it (instead of refactoring it) due to time constraints. Couple that with working in a team of developers and comments become the norm. Unfortunately, we can't base our assumptions that the whole team will make good code and not create ambiguity with their naming.

If you don't work in a team, then by all means, don't use comments, that's what I usually do 99% of the time in my personal side projects.

Believe me, I wish we could simply get away from comments altogether since they:

Aren't linked to what the code actually does (changing code doesn't change the comment and vice-versa)
Are mostly boilerplate and sometimes add tons of unnecessary lines in our code.

I agree, but it depends on the language. In a strongly typed language that is usually the case but when you don't even know what is the type of data that the function returns then you might need some comments.
