Tangent: I find it interesting that Erlang is an emerging technology that you are interested in learning at age 50, and yet it has been used in production with a steadily growing community since you were in your 20s. It has simply taken a few decades to grow enough to be a common item on programmers' radars.

I find it fascinating that the gradual adoption of new technology maps onto human time spans like this. This makes me optimistic that even technology that is far ahead of its time can succeed when developed with patience.
