What is social media meant to achieve?

Social media meant to achieve something that wanted to achieve by its user. I just want to share lines from one of the user in a social media forum...

"For a person who loves to communicate, social media is used to satisfy.

For a business person, social media is used to promote.

For a Cyber bully, social media is used to destroy.

For a peace maker, social media is used to convey..."

This means that social media, aims for anything and everything that its user wanted to achieve.
