In Because Internet, Gretchen McCulloch argues that there are three waves of "internet people". The first was "before it was cool", the second when it became mainstream (give or take the turn of the millennium) and the third when internet was already a thing. The third are young people, too young to remember the 1900s and therefore the time before internet, and old people who go online because it's unavoidable and also more intuitive and easy than ever before.
Despite the generation gap, they have things in common and in contrast to the first and second wave (which she also subdivides but that's beside the point). For example they never used mail as primary communication and they have smartphones as first device and most often second hand from a family member.
Thanks for listening to my Ted Talk and sorry if I took your shitpost too serious but there's truth and science behind it and I couldn't not share it.
