I was thinking about the learning part, as I’m investing a lot of part learning the phoenix/elixir ecosystem. On the one hand I feel it may be going slower than before, but I’m not sure if it’s because some mental decline or I just know a lot more now and every time I learn some new mechanism I run through a bunch of scenarios in my head from previous experience and have to integrate it with existing knowledge to make it stick.

I can no longer just learn the syntax for how the pubsub works, I have to stop and think how to build an architecture around it, how to create an abstraction for my use case, can it be integrated with Postgres triggers etc.
