> I echo others here - I've not seen a meaningful, revenue-driving conversation happen in these in a decade of work. Do you have specific examples of valuable collaboration in one of these environments?
Maybe it depends on the company (specifically size and bureaucracy) but many of the most successful ideas we've implemented in companies comes from employees having beers together after work discussing some crazy idea, or while lunching in the cafeteria and babbling about "how things should be".
I remember a specific incident when a colleague was lamenting about some hard-to-solve big to me while we had lunch, and another person who wasn't really in the conversation overheard, and finally had tips to solve the problem which ultimately lead to my colleague to being able to solve it.
As a more famous example, Bell Labs had tons of hallways and other "infrastructure" that facilitated impromptu meetings like this, and cites the design for some of the ideas that sparked from it. If I remember correctly, some new entire buildings were built with this in mind.
