Very good points indeed.
I shut down any and all electronic devices about an hour before I go to sleep, and when I started doing so ~4 years ago, I instantly noticed drastically improving sleep relaxation. Together with release of toxic thought patterns and consequent physical body density release, there has almost never been a day when I didn't wake 100% comfortable on every level. As so often, Humans ignore things they cannot perceive with their eyes. If they were to see the electric energy floating around hither and tither, some people would probably rethink this issue.
And yes, the social aspect is not to neglect either. Especially in the wake of my Spiritual journey I have found superficial exchange of words absolutely superfluous, and I don't take stock in learning some phrases learnt by heart, which then allow me to call myself apt of "social know-how", a thing having increased due to technological impact of smart phones etc..
Authenticity is the panacea in every social interaction.
Yeah small talk is a waste of time for me too... so much more important things to talk about :P
