Digitization is a trend we've been seeing in conservative industries for the last 20+ years when Windows 95 started to ship to the end consumer and companies now had the ability to give people without any technical background the chance to become more productive and embrace software like email for day to day business.
Do you remeber the time when SMS was a thing and all the kids were doing it and how it transformed the way we treated emails more like chats and everything became more informal? Then came the smartphone and made us all addicted to it. Seriously, just look around you on the street, in the tram or on the bus. So there is definitely over-stimulation of our senses. Less and less people are actually calling each other on the phone, in fact I observed a trend in sending voice messages instead of calling - using apps like WhatsApp or Snapchat.
