Access to information does not mean consumption. If you give access to internet to 100 people, 99 of them will use it for Facebook or Porn.
1. If you have enough motivation, learning about anything was already possible even before Internet (local libraries and resources)
2. If you don't have enough motivation, then providing access to Internet, is not going to make a difference.
So the key to a smarter planet does not lie in providing internet. But in installing enough motivation, imagination and a quest for knowledge and free thought in younger generations.
But sadly, the Internet of today seem to work against this by providing perpetual distraction and addictive/useless chitchat across the world......
