Going on golf courses together, dining with the team etc. are the traditional recipes to create trust. But it's walking that fine line between personal and professional life, while also bridging the technical abilities parts and the personal chemistry parts.
I understand we are all human and personal feelings have an impact on work, it can't be extracted up to a point. I'm just not sure we should see it as something that should be perpetuated, moved online or adapted to new environments if those were by default devoid of these elements.
Basically I'd hope we can prioritise other ways to create trust than building personal bonds (TBH, being good at one's job for a decent amount of time seems plenty enough to me)
