> In the past, offices were a great way to meet new people. I would suggest that your work office is not a great way to depend on meeting new people. Aim to meet new people at social settings, not business settings. Join clubs and go to social activities to meet new people. Sports, culture, arts, etc. Spaces that have zero to do with your work or profession are key. I'm in the Army Reserve to meet people outside work…
Depends on the office. Some are vibrant and full of interesting people!
The issue is that you’re creating a single point of failure, as OP was asking. If the office shuts or people leave or you need to leave or there’s some issue at work, you can have lose both your social group and your work in one go.
