Having a degree in a specialized field (like engineering) can help meet requirements of a potential employer and make a person look good on paper.
But any piece of paper is simply a piece of paper. It's the journey that counts.
The world is full of self-serving well educated fools. Who derive hubris from some type of certification which blinds them to the actual reality of life. If the idea is that you may look a bit more competitive (to do something you'd like to do in your life--potentially opening some doors) and do the task to better yourself and learn something useful it's a great idea.
Otherwise, the money might be better spent in a brothel.
