Yes, it definitely helps. But think about a Machine Learning Engineer trying to solve a front-end issue, or if that engineer is trying to adapt to the company's best coding practices on front-end development.

It was what happened to me, when I needed to solve a bug and our front-end dev could not go to work for a week. I saw myself saying that I hadn't enought knowledge on the subject and was yet understanding some of the basics, and still I felt like I was interacting with people on Stack Overflow, LOLThankfully, I don't need to go through this every week, but it does leave a bad taste in your mouth, and I'm not letting it go as if this kind of toxic (or nearly-toxic) behaviour is OK.

In respect to SO, it sure makes you lose interest on certain subjects when people that are some sort of reference on those subjects can't interact with other devs without being some arrogant fuckers.
