Imagine engaging in small talk with a stranger, and then a few minutes later another stranger approaches you to continue the conversation.
After 10 or so encounters, perhaps the (branching) conversation could go well beyond small talk and even lead to work opportunities, for example.
Of course, participation would be restricted to consenting adults, with strict privacy protections (e.g., a full data wipe at the end of the day).
Has anyone tried to build something like this?
