Yea this is a good one but it can be so hard. Seems obvious that constant information streaming outside of silencing your own thoughts also makes the moments where you do have to sit in silence lower quality.
I recently listened to the Hammock Driven Development talk (https://www.youtube.com/watch?v=f84n5oFoZBc) and it raises the very interesting point that it's not really the concious mind that makes big breakthroughs on hard problems, it's mainly the subconcious mind synthesizing information. It seems obvious to me that constantly intaking information will ruin this synthesization.
Sadly for some reason our brain loves filling the silence with junk...
