Im originally left handed, yet was made to use my right hand to write. I'm a diesel mechanic and able to utilize both naturally. Although I cannot write with my left hand I am mostly Ambidextrous. So what does that say fo people like me.

You could say that one side is too emotionally motivated and the other is too logically motivated I guess. We have to find that sweet spot in the middle that will allow the right amount of logic and emotion. Sadly, that's clearly not an easy task with such a diverse world.

It's not an either or. We all use all parts of our brain. Some use the right hemisphere more and some use the left hemisphere more. And yes, we need both 'types'.
