My first job had a strong lunch culture, providing an environment for serendipitous conversations, daily. Over time, I bumped into folks I never would have met in the normal scope of my role, across finance, legal, SRE, support, sales, data science, etc.
In turn, as a young professional, I was able to develop a mental model for how businesses "work", why they're organized how they are, and how (good) culture can bind everyone together towards a profitable outcome. I made some friends and acquaintances that I'm still in touch with to this day.
As a remote, older professional now, I don't necessarily "need" these serendipitous conversations anymore, although I miss the general socialization. But I do feel like they're an essential "ladder" that every subsequent generation of professionals should be able to access, and that it's a moral obligation for me to "pay it forward".
For remote work to be "fair" to young professionals, its systems should facilitate the same career benefits, with the same effort.
