I doubt that technology in general causes loneliness but there has been research showing that those who use more social media are more lonely.

I wouldn’t say technology is causing loneliness but the ways that technology is applied to social situations can cause loneliness.

For example:

• I would of thought the printing press served to inform people of news, helping reduce the feeling of alienation of people who are different.
• Using video conference software, such as Microsoft Teams or Zoom, to facilitate working from home will make us more lonely as we are able to communicate less frequently with others and there are some ways of communicating that are hard to facilitate over this software.
