A lot of this comment isn’t born out in reality. Around 30% of marriages in the US are from people who met in the office, plenty of people make life long friends from people they met at work, etc.
I’m not saying that should be the primary place you look for friends or an SO, but plenty of people are successful doing it.
It's true that a lot of it happens that way. It's not particularly healthy and has extreme side effects in situations like the one at hand (suddenly moving to full time remote) People should diversify their social life.
So I shouldn't become friends or lovers (when hierarchically/power dynamic appropriate) with people at work just because I might go full remote at some point in the future?
This becomes a bigger topic but if those people never had worked together they probably wouldn't have met and more over is that a initiated out of convenience or pressure of having to date or hang out with a co-corker because they are always around and you have to see them frequently or daily?
What happened to meeting people naturally outside of a forced setting?
I mean if you are somewhere 1/3 of the whole day you naturally get to know the people you are around everyday. As well as the fact that you already have a filter of commonality, everyone I work with already has been filtered to live in the same town, at the same company and is also a fellow engineer. No one's harassing someone into dating them due to being around them a lot and if they did that sounds like some type of #metoo situation and probably would get you fired pretty quickly nowadays. If you don't want to date a coworker you are free to not date them but I don't see how, for example my coworkers that just got married have an inferior relationship because they didn't meet 'naturally'. In fact I would consider getting to know someone by talking to them everyday one of the most natural forms vs meeting someone online.
