Comment by Mev-Rael on "How important it is for one to know the internals of a tool, language, or framework which they use on a daily basis?"

Should surgeon know the medicine and anatomy before doing operations?

Will you go to a dentist and allow him to work on your own teeth if he has no understanding on "internals" about your teeth?

Will you register on a website and put your password in the DB knowing that it was developed by a person without a necessary knowledge?

I'm sure you know the answer to your question and let me underline the main part of it - "on a daily basis".

“You can only fight the way you practice” - quote by Miyamoto Musashi

And if there is no practice (knowledge) then you can't fight (apply) it in a right direction.
