Despite of the fact that I'm not a religious person I would like to say God bless those people who invented the Internet and online communication as the result of this invention. It has a lot of contradictory pros and cons, but my life is completely changed with it in a good way.
Firstly, I want to start with disadvantages of the online communication. The first one is not having online communication etiquette. People can write you after your working time, especially during the COVID-19 pandemic when people "take" their offices at home. It completely erased the boundaries between work and rest. The second disadvantage is a decrease in real communication between friends. It's much easier to write a quick message than finding a place, a reason to meet and actually go outside.
However, humans have a huge amount of advantages with online communication. For instance, today I wanted to know if it's safe to use sunglasses repaired with super glue. I couldn't find this information online so I decided to ask the manufacturer of this glue. I wrote to their email and in two minutes I got their answer. It's awesome! It can't be possible without online communication. Secondly, I have the opportunity to work online, speak with people around the world, Skype my parents when I'm not close to them and so many opportunities that weren't possible before the Internet era.
To sum up, I should say that I'm not sure how online communication will influence the world in the future. Although, I really feel that right now, during these pandemic restrictions, communication online is the thing that doesn't let people go crazy and it's really valuable.
