This video starts from the assumption that face-to-face communication is better and preferable to online interactions in every way, which is not true. It also implies that online interactions are weaker, more superficial, and that IRL interactions are "superior".
I think that both ways to relate to other people are equally as valid, and the Internet allows us to create some relationships that couldn't have possibly existed otherwise, and that couldn't have been replaced IRL. I could have more friends around here (except I'm a big introvert so probably without internet I'd have the same amount of IRL friends I currently do, but zero online ones- hurray for socialization!), but that would not make up for meeting people from different cultures, countries and races I can't find around here. And widening your horizons, even if it's online, helps you develop your mind much more than having three more friends from your neighbourhood.
