Losing or have we already lost it?

Food for thought, enjoy, I personally found it pretty interesting.

How much have we lost in intelligent thinking? How much have we lost in communicating with one another?
Hmmm... I worry,

I don't think people give enough credence to how our environment affects our thinking and how thinking a certain way reinforces itself. By making everything convenient and easy we've put ourselves in a circumstance were we learn to think conveniently and easily. Higher though requires effort.

Interesting thought, hase tec made it easy for humans not to think as much? It certainly seems like some people don't think enough. Not thinking much must weaken the brain like an unused muscle grows wear.
