I'm afraid that there will always be an underwhelming minority of technology users who make conscious choices to purchase and encourage calm technology.
One admittedly tepid hope is that society-scale evolution will eventually help. Communities that embrace calm technology will be more fit and ultimately successful than those that acquiesce to jarring, rude, and disruptive technologies that foster a passive, frantic, reactive, unreflective, and anxious consciousness.
I totally agree with this and love the calm technology principle as well. I'd like to draw attention to the "Time Well Spent" project started by Google's "product philosopher," as I think it's very similar and equally as important. http://timewellspent.io/
