Earlier quoted context omitted.
If you can connect or collaborate in a hallway, you can also do so in a Discord channel (or whatever tool). There are also several good applications for internet collaboration that simulate a rich shared 2d or 3d or video space. Or things like GitHub issues and Wikis. Networking, mentorship, company culture, etc. can all happen over the internet. You make it part of the company culture to use the remote collaboration…
Discord, rich shared 3d spaces, GitHub Issues, wikis... Lol. Some people (most, I'd say) prefer going to lunch or to Starbucks with other people, leaving all the technology behind briefly, and simply talking. I think it's also more effective in getting a point across than any virtual medium.
It's nice to be able to meet in person sometimes and going out is more fun. But it absolutely is not important for effective communication. Unless they literally have poor writing skills and/or poor reading comprehension.
