Try volunteering. I had this exact conversation yesterday on a firetruck on the way back from a hazard reduction burn, that one of the things we all valued most about our volunteering experience was that we were exposed to people we wouldn't normally hang out with in our professional or social circles.

That said, on this particular truck three people out of the crew of four were programmers. We thankfully pulled up the conversation about the merits of Jupyter Notebooks for BI tooling before the fourth crew member, who is studying forensics, got so bored her eyes rolled right out of her head.
