Sorry, but even though we know social media has its downsides, it also has advantages: keeping in touch with friends, socializing, a way to stay up to date with your community, new recipe ideas, exercise ideas, time management ideas, maybe even the occasional envy that someone's success triggers more ambition in you to succeed etc.
It's a tool, like any other, and if used properly it can enhance your life.
Don't want to dunk too hard on this article, because the points made in it are valid. But they can be achieved while you're still active on social media.
For example, if used properly, you can get exposed to a lot of novel ideas in 2-minute bite sized clips. You can get motivated to hit any of the points mentioned in the blog.
Saying that, of course the article was written to be a very one-sided view on the topic. Given that, it's obviously going to be shared on social media and garner even more attention / clicks / eyeballs. It's not ... irony per-se, but something close to it.
