Moments of Zen created by stateless systems

Just been struggling with a problem in Phoenix Framework, which led me to reasoning about the pragmatic implications of stateless systems in non-programming contexts. I didn’t even solve the problem yet (I refuse to use JavaScript, even though it would be easy in that), but I’m just sitting here with the vague feeling of being in awe.

I wonder if anyone else ever feels like this? In some ways it reminds me of when I first started learning Ruby, but it’s different somehow.
