There are different people with different opinions and each of their opinion makes sense as each of them have valued points that can explain the reason for their opinion.
If I say yes, that WhatsApp, Instagram Facebook, Snapchat are killing the creativity level of a person and the reason behind that the people who can be more creative in the real life are spending more time watching the videos, chatting and clicking pictures, etc and they are always on their phone showing off their lifestyles to the world . Social media is more important for them than the real world, how many likes they got on the picture, what are the comments, how many views got, number of followers and competition, comparison these are all the things that a person experience on social media. But they can spend there day being creative in there life.
If I say that, no WhatsApp, Facebook Instagram and Snapchat all things are in fact helping the artistic and talented people to present their talent and finding the people who respect their talent is also true because we can see online, that there are so many dance video and singing video painting videos, showing their makeup art and their drawing, sketches, etc. They are able to connect to their old friends and they are gaining love, respect and attention that they deserve for their talent, that they don’t get in real life or they are just getting the spotlight from the social media platforms
Both of opinions are correct depending on person to person. It depends what they are doing on the social media. Is that productive or they are just using social media to relax and explore, it is also important that the excessive use of anything is harmful and not utilising your resources is also not good. So you should balance out everything in your life.
