I’m a millennial computer scientist who also writes books and runs a blog. Demographically speaking I should be a heavy social media user, but that is not the case. I’ve never had a social media account.
At the moment, this makes me an outlier, but I think many more people should follow my lead and quit these services. There are many issues with social media, from its corrosion of civic life to its cultural shallowness, but the argument I want to make here is more pragmatic: You should quit social media because it can hurt your career.
