Well, perhaps you are right and this is the ultimate natural selection. And maybe we will be free to perform other activities that are much more relevant to our existence. But the brain is a well-oiled machine, and the less you use it the rusty it gets. If the glasses tell you exactly where to go all the time, we will lose spacial orientation perhaps. If the glass makes all the math for us, we will lose our computation abilities.

Furthermore, this will make you highly dependent on a device that could ran out of battery or connection. How will you perform computation that you need for decision making then? Let's take it further, why go to universities when Google Glass tells me what I need to know?
