Thanks.

One nice side effect of having done this is having a small rolodex of other people who are like that.

So, like, if I had a good use case for Elixir and wanted a pal to hack on that thing with, I know a handful of people who I'd call, none of whom have ever used Elixir before but I know would be excited to learn.

Yes, same here. And that has come in very handy more than once. But my merry band of friends isn't getting any younger, I think the youngest in our group is now mid 30s or so, the bulk between 50 and 60.
