The ideal to strive for is what we call the "Goldielocks effect".

Not knowing too little. Not knowing too much. Knowing just enough to get the job done.

In computing there will always be multiple solutions, and tradeoffs. What you want to aim for is "The simplest solution possible."

In my experience, this is really hard for most developers. Maybe the smart thing to do is find someone who makes it look easy and trust their judgment. Again, my experience is that most developers are reluctant to do this.

The question is not how much someone knows, it's whether they know "enough" to get the job done. Goldielocks.
