Yes I agree
Lots of the other posters have a point -opening up the field etc.
But loads of the close friends I have now come from previous jobs. Even those I haven't stayed in touch with made the job at the time so much easier.
I also think work is often one of the few places where different generations and people from different backgrounds get to mix together. Once you've left school, unless you have a hobby that attracts a diverse group the vast majority of people's social network consists of people the same age/life stage/background as them, which is how we end up in echo chambers.
Gen Z in particular seem really siloed in their thinking and there's so much media highlighting stupid generational differences, if people never get the chance to interact with others and realise we have more in common than we have differences, those stereotypes will become entrenched.
I've started a new job fairly recently, completely wfh and it's HARD getting to know people when you never really "meet" them, compared to when you sat next to them for 40 hours a day and ate lunch together. As willing as people are to help you do feel different about bothering a complete stranger you've never spoken to with a teams call when you have a question, not knowing whether you're interrupting them or not, rather than wandering over to that guy you've chatted to a few times in the kitchen when you can see he's not busy. I can manage it because I've got years of work experience but can imagine it could be really hard for a new grad.
From friends' anecdata ive heard loads of other workplaces are struggling with the same issues both my old and new workplace has -people wanting to wfh but feeling disconnected from their colleagues and not a 'part' of something.
On one hand I feel guilty about "pulling up the ladder behind me" because I benefitted hugely from working alongside older and more experienced people when I started. But on the other hand I don't want to go back to the office full time either!
