you have no choice.

Everything around us has been made with functions and closures. Give 
someone a function to call you back, and they call it a callback. Phrase 
"Observables and Promises are fancy callbacks" I've heard in pure form 
from Rust guy. Precisely. It comes from Lisp and builds the future in 
Rust. We either do assembly with jumps, or we do callbacks.

Granted, I love to consume cakes (Observables and Promises) instead of 
straight sugar (callbacks).

Not loving and groking callbacks is not an option -- debugging becomes 
nuts :) . Yet, there is not need to take it pure all the time.
