I don't know what Internet does to our brains but I have observed few useful things. One complaint about Internet and whatever is that it provides all this emotional stimuli which is too easy to get hooked on.</p>
1. After a longer hike my brains kind of "reset". I don't feel like I'm in a constant hurry to anywhere. I can enjoy smaller things in life. Like a nice cup of tea.
2. Meditating somewhere outside civilization makes me highly creative. I get all these ideas, but when I come back to civilization I forget about all those ideas.
3. There was a recent article about the decrease in creativity / versatility in music by social media. I also find this to be true for any kind of innovation.
