Being modern and sophisticated can have different meanings for every individual. As long as clothing and looks department is concerned, I personally think that I am the least concerned about the same. In fact, I am being aware this case of people making accounts in the name of parents, only after reading the words from author.
From where I stand and live, the definition of being modern and sophisticated goes like this... Whether it is girl or guy, they are always dressed well and EverReady for taking selfies. Most of these pictures are overly filtered by different apps and features like Beautify, Big Eyes (almost like grey aliens) which only hints one common fact; They don't find them good looking without those filters. After applying enough shades and filters, they become modern. In fact, many selfie addicts have many pictures with themselves, friends, strangers but none with their own family. Even while being with their families, they are actually busy with their smartphones for normal browsing or chitchat, so much so that they can be assumed as not existing where they are physically present. Whenever you meet people, they don't look much interested to actually talk to you. Instead, they will insist you to connect with them on WhatsApp. And then after a casual hi and hello, all that goes on is some jokes, photos and data eating videos. In fact, many of us will notice that they person who has been sending such media to us over all these months has not actually talks or chatted with us since decades. That is the new thing in about being modern.
Regarding other things, I think everything that we are faking nowadays is simply what is called as the new definition of being modern and sophisticated. It is all about being formal and then faking everything to the core.
