If your business model includes: "we put people in an office in the hopes that their random interactions will create value"...then that sounds like the problem is something else.

Random encounters that create value sound good. It sounds less good when you flip this logic, and ask whether the reliance on randomness is a function of weak information-sharing within formal structures. It is easier to break down silos if you put this online, then there is genuine sharing. That is what the internet is for.
